Dale Armstrong (1941 – November 28, 2014) was a Canadian drag racer and crew chief. After winning 12 National Hot Rod Association (NHRA) and 12 International Hot Rod Association (IHRA) events in the 1970s,[1] including the Pro Comp title in 1975, he became Kenny Bernstein's crew chief.[2][3] The combination produced four consecutive national championships in Funny Car (1985 to 1988) and another in Top Fuel.[2][3] Bernstein became the first driver to top the 300 miles per hour mark in an engine tuned by Armstrong.[2] Armstrong has been inducted in numerous halls of fame. He died on November 28, 2014, at his home in Temecula, California, at the age of 73. He had sarcoidosis.

♪ [music] ♪ (Chase Pilot) NASA ONE: We have an ejection, we have an ejection. The aircraft is descending over the North Base area. I have a chute. The pilot is out of his seat and the chute is good. Control Room: NASA One, we copy. (Rogers Smith) We had a highly competent team, very experienced, many flights under their belt. We had a number of pilots that flew the airplane. The pilot in particular that was flying that day had been on the program from the very beginning. Highly experienced with the X-31. Each mishap has its own circumstances and it's own sequence of events. But you find similar issues: communications, complacency, assumptions that haven't been warranted. Human frailties. And you have to account for these things in a program. (Rogers Smith) Just like a chain. You make a chain when you have any of these accidents. A chain of events. Any link of the chain, if it were broken, you would not have an accident. This was the A team. We had the best people from every discipline, from every organization. And we lost an airplane. So, if it can happen to the best team. It can happen to any team. (female narrator) The X-31 research effort began in the late 1980s as an international program involving DARPA, the U.S. Navy, Deutsche Aerospace, the German Federal Ministry of Defense and Rockwell International. The program's goal was to explore the tactical utility of a thrust-vectored aircraft with advanced flight control systems, using an aircraft designed and built specifically for that task. The X-31 was a real pioneering program. In fact, the X-31 program pretty much wrote the book on thrust-vectoring, along with its sister program, the F-18 HARV. The initial X-31 flight tests were conducted at Rockwell's facility in Palmdale, California. But, in 1992, NASA and the U.S. Air Force joined the X-31 research team and the test flight program was moved to the Dryden Flight Research Center on Edwards Air Force Base. And before too long, the X-31 was turning in some extremely impressive results. [Jet engine] By any measure, the X-31 was a highly successful program. It regularly flew several flights a day, accumulating over 550 flights during the course of the program, with a superlative safety record. And yet, on the 19th of January 1995, on the very last scheduled flight of the X-31's ship #1, disaster struck. This particular flight had been on the books for some time to get done. And it was by our standards, an absolutely routine flight. We were not expanding the envelope. We were not trying anything new. We were flying a new pitot static tube... but this was a routine mission, a routine task, a routine flight environment with an experienced pilot and an experienced crew. But while the flight was routine, there had been some changes to the configuration of the X-31 since its initial flights. In particular, the original pitot tube, which supplies airspeed information to the plane's flight control computers, had been replaced with another kind of pitot tube known as a "Kiel probe." The Kiel probe gave more accurate airspeed data at high angles of attack, but it was more vulnerable to icing -- especially since the Kiel probe on the X-31 did not have any pitot heat. (Fred Knox) We were never to fly the airplane in ice. That was a prohibited maneuver. So, if you're prohibited from flying in ice, you don't need a heater. Normally, the conditions at Edwards are warm and dry enough that icing, or pitot heat isn't a concern. But January 19th, 1995 was not a normal day. The unusual part of the day was we had a high humidity at altitude actually conducive for freezing conditions and the airplane was operated for, in and out of some fairly high moisture content for extended periods of time, lead to some indications in the cockpit and the control room that was causing problems with the air data system. [Jet engine] (Dana Purifoy) This particular airplane had a limit to not fly through clouds, through visible moisture. That day, we were flying very close to and occasionally in and out of very thin cirrus clouds. It didn't particularly worry me because everything seemed to be going along quite normally. But some minutes, like five, before the airplane went out of control and the pilot jumped out, the pilot observed that there was some moisture around where he was. So he turned the pitot heat switch on. Now clearly, when he turned the pitot heat switch on, he expected that the pitot heat would be working. About two and a half minutes later, which is two and a half minutes before the accident, he mentioned that fact to the control room. Mysteriously, to this day, the control room gave him no response. They had an internal discussion as time, the clock clicked down. And internally it was commented that the pitot heat was not hooked up. But this vital piece of information was not relayed to the pilot for more than two minutes. And even when it was, the information was not stated as clearly or strongly as it could have been. Control Room: ....And pitot heat. Pilot: We'll leave it on for a moment. Control Room: Yeah, we think it may not be hooked up. Pilot: It MAY not be hooked up? That's good. I like this. We had side discussions that should have been going on on the intercom so that everybody in the control room was part of the conversation. Instead, we pulled our headsets aside so that we could talk to each other because we were sitting adjacent to each another. And that's another part of just control room discipline that we broke down on. Meanwhile, the first signs of trouble were beginning to appear. So now the pilot sees an anomaly in his airspeed. He's at 20 degrees angle of attack, and he can see that. And he's says to the ground, and I briefed this many times, he said, "I'm at 277, I mean 207 knots." Pilot: The airspeed is off. I'm reading 207 knots at 20 AOA ....Ok, pitch doublet. Well, anybody that's been on the program, and lots of people have been on many years, would know that 20 degrees angle of attack is somewhere around 135 knots, 140 knots. It's NOT 207 knots. Apparently, no one in the control room caught the possible significance of that discrepancy. And perhaps even more importantly, neither did the chase pilot -- for the simple reason that he couldn't hear any of the pilot's transmissions. We had a mechanism of hot mic. It was very important to the pilot of the X-31 that he be able to talk to the control room without having to press buttons at certain key times, especially at high angles of attack. Which was not going to be a factor in this flight because it was going to go to about 20 degrees angle of attack. But, it was a general operating procedure that was compounded because our hot mic system didn't work always very well. And when it didn't work, it put a lot of static in the earphones of the chase pilot who wanted to hear the hot mic to know what's going on. So it was the one-sided nature of the communication that kept me from having the situational awareness to be able to step in and say, "Hey, I'm reading X knots, and you guys are reading Y knots and these two numbers should be the same and they're not." The X-31 did, indeed, have an air data problem. The unheated Kiel probe had frozen over in the cool, moist conditions, causing it to start giving incorrect airspeed information to the X-31's flight control computers. In terms of the accepted risk, the failure of the pitot static system or damage to it was well known. It was well understood. The pilot himself had simulated the failure in simulations before we even got the airplane. And it probably helped him understand that he had to get out of the airplane because the time is short when the airplane is diverging. And we went through quite a thorough review of the hazards that we knew or could come up with based upon the design of the flight control system. And we thought we had a good handle on that. We thought we could lose the whole nose boom. We could take a bird strike, wipe out the whole nose boom and fly home safe. As a result of that, we thought we had a pretty robust system. The reason the team thought they HAD a robust system was the X-31's flight control system was designed with three back-up reversionary modes the pilot could select in the event of an air data problem or other systems failures. So in the case, of if you saw something that was not right or the control room saw something that was not right with respect to the airspeed system, they could tell the pilot to go to R3. R3 was a reversionary mode that would have removed -- within 2 seconds -- the airspeed data inputs into the flight control system. The control surface response to pilot inputs would then be independent of airspeed allowing the airplane to remain controllable for the remainder of the flight back to the landing. The accepted risk was probably reasonable. But here's the kicker...the consequences of a failure are so high here that you really needed to put some special attention on this. The designer did by putting R3 in. But nobody on the test team, including the pilot, realized that the X-31 was experiencing an air data problem that would require implementing the R-3 reversionary system. For several minutes we had indications that airspeed was becoming poor, both in the cockpit and the control room. In our last ditch catch, nobody stood up and yelled, "Wait a minute, this can't be right." Because had we realized what was going on, the control system had the ability to go to fixed flight control gains. And with fixed flight control gains, it would not have been a problem. They would have been able to land the airplane safely. But we just never got enough information to make the decision to do that. We had an alternate airspeed indicator that used a different pitot tube which would be less susceptible to icing than this special tube. It was at the pilot's right hand knee. And he never looked at it. We had a lack of attention to the reversionary modes. Gradually, we were not thinking. We learned to depend on the control room -- they're going to tell us when we need to go to R2 or R1 or R3. We need to know as pilots, which we kind of forgot, where are the safety nets. The safety nets - push the right button - didn't get the test data, but you bring the aircraft back. So if we didn't understand what was happening, we should have been constantly reminded, push the button and talk about it. The pilot obviously wasn't concerned. He was experienced... Probably, if you look at the control room, the pilot and everybody involved in that day's activity, he was the most experienced in that day's activity. He'd been on the program since Palmdale. He noticed something but he wasn't concerned. And he didn't ask for help that I was aware of. So I think the control room said, "Well, if he's not that panicked, I'm not that panicked." And I think that fed off each other a little bit. The team moved on to the final test point of the day -- a simple, automatic control response test that required only a command from the pilot to initiate. But once again, the airplane DID NOT respond as expected. He hits the box, presses the button and he says, "I don't get anything." Well, he didn't get anything because the box was designed not to put any input if you went beyond a certain speed, like 200 knots. So it was seeing the false airspeed of 200 plus knots and when he pushed the button, it didn't work. Pilot: Three, two, one, go. Hmm. It doesn't do anything. Well, it didn't work because something was wrong! And, the control room came back and finally just kind of ignored that and said, "It's all okay and RTB now." It's almost like expecting to hear that it went fine. After this program with hundreds of flights and everything going perfectly, in your mind, you're hearing things that aren't happening. Everything's fine, it worked fine, let's come home. The normal operation of the system was expected that the system would identify the problems itself that it would not be the people on the ground identifying an air data problem and calling for fixed gains. Although it was certainly capable of doing that, the expectation would be that the system would do its own self-diagnosis and identify failures. But the failure we had was a slow failure of the tube, slowly building the ice up. So the changes in the speed were within perfectly reasonable numbers for a real airplane. The software's just not capable of detecting that failure, for that system. There was one or two people that actually knew that there was these little tiny areas that it couldn't handle but that word never got out. They never stood up and said, "Uh, boss, that's not quite right. You can handle it over 95 or 99 percent of the area but there's really a couple little areas that the automated system can't handle." And that didn't come out until after the accident. I never did get to talk to them about it but I just kind of felt like they didn't want to stop the program, thought it was of no real issue because of the difficulty of getting to such a small area of the envelope. But as the X-31 began to descend on its return to base, the problems caused by the failure of its air data system became far more pronounced. We have frozen the pitot tube now. And it's stuck. It's got what it had in it and it's going to hold that pressure. Now when you start down with a frozen pitot tube, the airspeed, what you see, the false airspeed that he saw, will decrease as he decreases altitude. But we are seeing, "we", the control room is seeing, they have a big display, the pilot is seeing every time he turns his head, he's seeing the airspeed in the HUD. And now, it's perhaps at one point, it's at 150 knots. It cannot be at 150 knots! And then it's at 100 knots and it cannot be at 100 knots! And going on down and finally right just before the accident, it gets to 48 knots which is the minimum it's going to read. But the control system in the airplane is getting this wrong information and this is a complex closed-loop system and when you put too much gain in, it will start to get unstable and it will start moving the controls, which it did in a matter of seconds. And finally, it dramatically pitches up, the pilot of course tries to prevent that and I'm sure the instant that he hit the forward stop and realized he was out of control, he did the natural thing which was to eject from the airplane. We were RTB (return to base) and I started to rejoin on the X-31. As I came up on his right side, about 100 yards away and closing I saw the airplane start to go into a small wing rock that progressively got larger and larger. And, as I got within about 200 feet of him, the airplane pitched up vertical and approximately the time that I passed abeam him, I saw the pilot eject. Chase Pilot Dana Purifoy: Okay NASA One, we have an ejection, we have an ejection. NASA One do you read? Yeah, we copy Dana, we copy. Puriofy: Sport, NASA 584 has ejected the aircraft and is descending over the North Base area. I have a chute. Sport NASA 850, how do you read? 850, say it again please? Purifoy: Yes sir. NASA 584 has ejected from his aircraft. The aircraft is descending north of North Base. The pilot is in the chute at this time, descending approximately one mile north of North Base. 854, copy. (John Bosworth) So there was the knowledge and training in the simulation that taught the pilot that when he started to see the airplane was oscillating and was not controlled, he knew he had to get out of the airplane very fast or else the airplane would go into a tumble. And he did do that and that saved his life. I also know that the pilot, as he was ejecting from the airplane, had thoughts of, "Maybe I should have tried a reversionary mode." But at that point, if he would have hesitated any longer, he would have been probably lost with the airplane. Stoliker: I did not connect, until after the plane departed, and while the plane was tumbling, I made the connection: the pitot system had to be frozen. And just didn't come to the realization soon enough to do anything about it in the control room. Less than four minutes after the first comment about pitot heat was recorded between the pilot and the control room, the X-31 crashed just north of Edwards Air Force Base. How could such a routine operation have ended in disaster, when flights with far higher risk had been completed safely? And more importantly, what can we learn from the answers to that question? Szalai: Every person involved in an experimental flight research program should actually study the mishaps of all experimental aircraft in the past twenty to thirty years. There's a lot of things you can learn. Because human nature doesn't change. The processes don't change. It's always the same set of contributing factors. Just the names and the details change. Of the ten things, for example, that I would describe as causes, contributing causes of the mishap, six of them occurred prior to the day of flight. Four occurred within about two minutes. So, we had a better chance of working on the six than we did on the four. In some senses, the X-31 accident started six years earlier, when the plane was first developed and tested at Rockwell. Knox: We had a hazard analysis from the initial design. And in the accident that had to actually get dusted off. You should never have to dust off one of those. Everybody familiar with the program, at all those levels needs to have a really good comfortable feeling of what those hazards are and what are accepted in the risks. There was a redo of that analysis as we moved to NASA in '92. And I think, that it was clear after the accident that not everybody really understood what that design was to the detail you needed to understand the full risks of the program. Clearly, from 1990 to '95 you have a large team turnover. We changed locations. We expanded the objectives of the program and as time rolls on and the new people come in, not everybody has the same understanding or appreciation of the kind of vehicle we're operating. It's a special airplane. It's not the same risk as any other airplane and to operate it everyday you really ought to have the same appreciation for the risk. And I don't think we, as a team, did a good job at keeping everybody that came to the program with the same level of understanding of both the design and the risk of the airplane. We shouldn't have had a control room, a pilot and a team that day that didn't understand that fundamental fact. And it's not elaborate. It's just straight-forward. The airspeed I see in the HUD is the airspeed the computer uses. If the airspeed I see has got a problem, the airplane has got a problem. And that fact didn't get communicated correctly from the old team members to the new team members and if it had, I don't think there would have been anybody in that room that wouldn't have yelled "STOP" and jumped off that bridge to make it happen. There were errors made. The pitot heat circuit breaker was disabled but there was no placard in the cockpit to say "NO PITOT HEAT." Notices of the configuration were sent around but here also we probably lacked one step and that is to know that everybody got the message. It's one thing to send it out, it's another thing to verify that everyone has read and understood it. And so that procedure was changed, by the way, so that people ripped off the bottom of the page and sent it back. I've seen it. Ironically, the X-31 program also may have been a victim of its own success. Szalai: I never saw complacency in this team. I went to tech briefs, crew briefs and it was treated very professionally and in fact, to some extent it was treated like an experimental airplane every flight. But certainly you have to think that after hundreds of flights, excellent results and the fact that none of these hazards, these terrible things that you predict could happen, has ever happened, it could lead you to be less sensitive to things that are happening. Maybe just a little bit of the edge comes off. Those single point failures were identified and we made some actual changes to the design of the airplane to account for that. Again, that was in 1989. Why all those were there and what the concerns were and how to mitigate them or how to worry about them became... we hadn't had any problems with that for five years and I think again, the complacency just got built into the team. It worked fine. We'd never had a problem. And those little hairs on the back of your neck weren't geared to stand up when people started having air speed problems. Our control rooms used to have a saying on them to, "Prepare for the unexpected and expect to be unprepared." And I think that's a truth in the flight test business that we need to keep in mind continuously. I wish that sign was still up there because that reminder needs to be enforced all the time. Well certainly in the case of the X-31 we were returning to base after two exhausting days, 7 flights. Ship 1 was now going into the boneyard or at least it was being retired from the test program and so we're finally finished. Was everybody paying attention like they should be? Obviously not. And while the X-31 program flights were highly successful, they did not include an element that might have helped prime the program team to take the one mitigating action that could have brought the X-31 home safely. We've debated amongst ourselves whether we actually would have been able to convince anybody to use the fixed gains system because there was not an obvious need for it. The pilot may have been better prepared when things started to go awry to select fixed gains but I don't know if we ever really would have done it in that situation because we didn't have a real problem. We DID have a real problem but it hadn't been diagnosed as a real problem. On a previous program, the X-29 program, we had the same sort of thing. We had an analog reversion mode, a digital reversion mode, and the normal mode of the airplane. We routinely at every test point selected those back up modes, flew them around so the pilots were much more familiar and much more comfortable with selecting those modes. On the X-31 program, we never selected those modes intentionally, we only used them when we had a sensor failure or when the system told us to select those modes. On the day of the mishap itself, there were additional links added to the chain. There were unusual weather conditions that created an uncommon and unexpected kind of flight hazard. And the team was working with a flawed hot mic system that kept the chase pilot from hearing critical communications from the X-31 pilot. So, some links in the chain are already built there. Management links. The control room has now talked internally, they've heard some things, they haven't said anything. Some more links are built. We've got this chain is building now. The chase pilot didn't hear anything about this, he didn't know anything was wrong with the airplane until he saw the airplane pitch up and the pilot jump out. Whereas he could have stopped this at any time. At any rate, it's a total team concept and the chase pilot has to be part of that team and the team has to have total communication. So the use of a hot microphone frequency that did not allow the chase pilot to stay up with what was going on with the airplane was essentially keeping me from doing my job at least at a certain level. And that's one of the things that we changed in the way we do business here at Dryden is to allow the chase pilots either access to the hot mic or to ensure that all critical communications are transmitted so that all the players are kept up to speed with what's going on. And that was a direct fall out of how the X-31 operation was handled that day. If one or more of these contributing factors had been caught and addressed prior to January 19th, the chain of events leading up the accident might have been broken before the flight even took place. Yet there were still opportunities to avoid the mishap, even in the last few minutes of the X-31's flight. So why didn't the team manage to recognize, communicate, and respond to the X-31's pattern of anomalies in time? Stoliker: So we were seeing inconsistencies between the data from the aircraft system and what we knew of the physics of the problem that it could not be, that you could not have that airspeed and that angle of attack simultaneously. And for me, I just remember thinking, "Gosh, I can't wait until we get the data from this flight because I want to see what's going on." I knew there was an anomaly. We had talked about it between the engineers. We didn't talk about it on the intercom though, it was sidebar conversations in the control room. Well, many of us are engineers and we see an issue and, "Oh, this is interesting, I wonder what's causing that." And you start thinking about it and trying to figure out what is the answer. In the meantime the seconds are clicking by. And really, the right response is, "Something's going on. I don't understand, let's call a halt here and let's just figure it out." We should have, at the first call of an airspeed failure, just puckered up. Whether you're RTB at that point or not, it wouldn't have changed. The kind of failure that was occurring should have triggered a lot of emotion anywhere in the flight envelope. In the case of any discrepancy, anything that doesn't sound right, feel right, smell right, let's stop and think it over. And I think that kind of attitude has been built in now into the mission control room processes since then. We were flying lots of flights. At the peak of the program there would be days when there would be five flight days. I think on that particular day we were only doing three flights and it was the last flight of the day. It was the last flight for the first airplane and we had completed all the test points for that mission. In addition, we were going through the RTB or return to base checklist and at that point, every one of us kind of relaxed. Like I said, what was going through my mind is, "I can't wait to get this data. Something funny is going on and I want to figure it out." And, that's another lessoned learned and we talk about it all the time, that the mission's not over until the airplane's on the ground and the engine's shut down. And you see it a lot in the control rooms, you start getting ready to land and everybody relaxes a little bit. And that's a lesson I've carried with me is that you need to continue the vigilance there on the flight. Communication is what it's all about. We have to have the communication links. We didn't have it to the chase. Hot mic was a contributing factor. We didn't have it in the control room. We discussed things internally, it was not transmitted to the pilot. We have to have an environment built where people can speak up when they THINK something's wrong. They don't have to be right. If they're concerned, they should be able to speak their mind, put their hand up and we stop the train and then we say, "No, you weren't right, it's okay." Fine, we go on. We didn't do that. We never stopped the train. We had a problem and we didn't stop, not only testing, but we didn't stop flying and come home. But you can't stop for every problem. That's unrealistic. You have problems in flight. The combination that went with that is that we didn't understand the severity of the problem. So you have to understand your vehicle and the consequences of failures. And if one of those failures has a serious consequence, you need to stop and come home. Clearly, there are lessons to be learned in the entire progression of events that led up to the X-31 mishap. And yet, the X-31 program did not end with that crash. The next chapter of its story is an equally important reminder of why flight test remains such a valuable step in proving a concept or technology, despite the hazards that come with the territory. The X-31 had been scheduled to fly at the Paris Air Show in June of 1995. But after the loss of one of the two X-31 ships less than six months before the show, it seemed an impossible goal. (Szalai) Having lost the airplane, pretty much everyone thought, "That's it." Because flying the kind of maneuvers that this airplane can do at 500 feet, sounded a lot riskier to me after you lose an airplane. The team really talked a lot about this and decided that it did not want to end this program on a low note and so we made the decision to press on with the Paris Air Show. A huge thing to sign up for was to take an airplane that just crashed and turn it around to go do a low altitude, high angle of attack flight demonstration. That took a lot of guts on everybody's part and a lot of good engineering work to make that happen. We actually flew the X-31 84 days after the mishap. This required the board to reach its conclusions, to write a report. For the team to react to all of the issues and problems and contributing factors brought up. Solve the problem and get it into an airplane and get it qualified for first flight. It was all done in 84 days. It does tell you about the quality of the team. Air Show Announcer: A totally different airplane which will demonstrate a most remarkable flying ability. It is the X-31 technology demonstrator. (Stoliker) You know, after the mishap, I think the program made a spectacular recovery and made one of the finest appearances ever at the Paris Air Show. The airplane did things that no other airplane could do. The Russians had demonstrated post stall maneuvers with the Cobra but it was really an open-looped maneuver. They pulled back on the stick and then you flew out of it at the end whereas the X-31 just demonstrated the ability to control all axis of the airplane, pitch, roll, and yaw simultaneously while operating at the extremes of the flight envelope. (Smith) So, fantastic Air Show. Absolutely the most spectacular I've ever seen and I saw every one of them. And I stood with the crowd on some of them and I was in the control tower on others and I was right underneath it at other times. But to be with the crowd and watch even hardened veteran's, the military, had no concept of what it could really do and seeing it was jaw-dropping for the crowd. It was spectacular. The announcement that the X-31 was next to fly, as you looked down the row of chalets, you see all the people coming out of the chalets, out against the railing to watch the flight. If the events leading up to the X-31's mishap are a reminder of how much vigilance is required in order to mitigate the risks inherent in a flight test program, the X-31's Paris Air Show performance was a reminder of why those risks are still worth undertaking. (Smith) Flight test of all kinds is inherently dangerous. There are risks involved in it. Never can you or anybody else bring it to zero. Well, you can, and that's keep the airplane in the hangar. Don't fly. But if you don't fly, you don't move forward, you don't discover, you don't prove things. So you need to take some risks but you need to do it in a controlled fashion. (Szalai) The reason we spend time on looking at these accidents is that there aren't many accidents. We don't lose many airplanes in flight research activities at Dryden. We haven't over the years. And so when you do have one, you better learn everything about it. In fact, you should do the same thing for close calls. The lessons to be learned. Don't assume that they've been learned. We can always, with every new group have to learn the same lessons and you don't want to do it the hard way with an accident. Safety is everybody's business. Flight test safety is everybody's business on the team. And, there are no processes... you have to have processes... but there are no perfect processes that will not require good judgement from all levels of the program. If you're a program that has been operating for a long time, potentially, and you've got a lot of turnover, you're in your mature years, all your documentation is years old. Maybe you better make sure that all your new people are as good as your old people. That you've reviewed your documentation and it's still correct and that you all understand it. And that what you're doing today still makes sense from how you started. Maybe if you're in that area you ought to take a look at yourself. It always is clear what you should do after the fact or should have done rather. And nobody thinks it's ever going to happen to them, to lose judgement, to lose this communication link, to not do the right things. So what is the message? What is the message for the team? It may mean that "I" am a part of the chain and that if I don't catch this and if other people don't catch their mistakes, we will run through the entire chain and lead to a mishap. So it means that every individual on the program, from beginning to end, no matter what the job is, from the highest-level job to the lowest-level job, in terms of detail, they have to take it very seriously. And, that's the message that you have to keep promoting, pronouncing, and explaining. It sounds trite but everybody is responsible for safety. If you think some safety office analysis is going to find these things, they won't. Mishaps can occur everywhere. But, the point is, you have to fly, safely... but fly. ♪
Career
Armstrong was born in Holden, Alberta, in 1941.[4][3] He bought his first car, a 1936 Ford Coupe, for five dollars at age 14.[4] In 1957, he began drag racing the car on a dragstrip at an airport near Calgary.[4] It took him five attempts to make a 60-mile-per-hour (97 km/h) pass; he took out non-essential pieces of the car such as the back seat to lighten the load.[4] His reputation for repairing cars quickly grew and soon there were cars lined up for repairs behind his family's garage.[4] He began drag racing in NHRA's Northwest division in a Chevrolet Z-11 in the B/Factory Experimental class in a front-ended machine that had 11-second passes at 115 miles per hour (185 km/h).[3] Armstrong and a friend towed his dragster to Southern California for the February 1964 Winternationals.[4] In January 1965, he moved to Southern California and began campaigning a Chevrolet II at local tracks since he could compete up to five nights per week.[4] He converted the car into a Funny Car and began running the car in early 1966 using the nickname "The Canuck".[3] The car appeared on the cover of Hot Rod Magazine in December 1966; the article in the magazine said "Even a diehard Chevy lover would have trouble telling just what had been the original vehicle".[4] The supercharged engine achieved runs in the 8-second bracket with a top elapsed time (e.t.) of 8.89 seconds.[3] In 1969 he drove a Chevrolet Camaro in the Super Stock class and he followed it up with making passes in Funny Cars "Travelin' Javelin" and Tom Strum's Swapper.[3]
Armstrong switched to the Injected Funny Car class in a 1973 Barracuda before moving to the new Pro Comp class in 1974.[3] He joined Ken Veney's team and beat Veney in the finals of his first A/Fuel event at the Winternationals.[3] He also won the AA/Altered U.S. Nationals for Jim Foust that season before moving to Pro Comp in 1975.[3] While competing in Foust's Alcoholic BB/Funny Car, he won the Pro Comp championship including wins in the U.S. Nationals and Worlds.[3] Armstrong continued racing in Pro Comp for three more years. During that time, he won eight more National events including the 1977 U.S. Nationals.[3] In 1976, he won seven of nine IHRA Pro Comp National events and the championship.[5]
He moved to Funny Car in 1980 and 1981 and had three final-round loses.[3] He used Mike Kase's Dodge Omni at the 1981 World Finals to set a national record with a 5.891 second pass to break Bernstein's 5.90 mark.[3] During the 1981 season, he had two accidents. Armstrong described the fiery 240 mph crash of his Dodge Challenger at Columbus, Ohio: "Yeah, that was kind of a bad one," he said. "It told me it was time to get out of driving."[4]
Crew chief

Armstrong joined Bernstein's team as his crew chief in 1982.[3] In late 1983, he took their new Ford Tempo-bodied Funny Car to a wind tunnel and found additional speed after some modifications.[3] Bernstein had a 5.80 e.t. with an all-time-best 260.11-mile-per-hour (418.61 km/h) pass in the 1984 Gatornationals finals to beat John Collins.[3] Bernstein ran third in points that season in his Budweiser Tempo.[3] Armstrong tested an on-board computer to see when the clutch was engaged and when the spark plugs were firing.[6]
Bernstein won the 1985 championship after winning six of 12 national events and reaching nine finals.[3] The Armstrong-wrenched Tempo set two national records during the season.[3] Bernstein continued winning in 1986; he won five of 14 events.[3] He qualified number one eight times, set the low e.t. ten times, and reached eight finals.[3] Bernstein had the first Funny Car 270 mile-per-hour pass at the U.S. Nationals (271.41 miles per hour (436.79 km/h) / 5.50 seconds) and lowered the record e.t. into the 5.4 second range with a 5.425-second run at the Chief Nationals.[3]
Armstrong continued as Bernstein's crew chief in 1987 and they used a controversial Buick LeSabre body.[3] Bernstein won a record-tying seven national events and achieved their third consecutive Winston points title.[3] The Buick had the first 5.3 second run at the Winston All-stars race with a 5.39-second e.t.[3] Bernstein tied another Don Prudhomme Funny Car record when he won his fourth straight championship in 1988.[3] His Buick Reatta made six finals, winning three times, achieved six low e.t., and qualified number one five times. In 1989, Bernstein finished third in Funny Car before moving up into the Top Fuel class in the following season.[3]
Armstrong continued as Bernstein's crew chief in Top Fuel, and the combination produced six wins in 1992 which tied a class record.[3] In 1993, Wes Cerny developed a cylinder head / magneto combination that Armstrong tuned for the first 300 miles per hour run.[3] At the Gator Nationals qualifying, Bernstein also set the record e.t. with a 4.823-second pass at 301.70 miles per hour (485.54 km/h) during qualifying for the Motorcraft Gatornationals in Gainesville.[3] Armstrong said:
Being the crew chief on the first car to run 300 means more to me than any national event win or any Winston championship. There isn't any question at all. People will forget what years we won the Winston championship, but they'll never forget when the first 300 was run and who did it.[3]
At the 1994 season-ending Winston Select Finals at Pomona, Bernstein broke the 310 mph barrier with 311.85 and 314.46 passes.[3] In 1996, Bernstein won the Winston Top Fuel championship.[3] In doing so, he was the first driver to win Winston championships in Top Fuel and Funny Car.[3] Armstrong became one of the few crew chiefs to win titles in both classes.[2]
Armstrong and Bernstein parted ways in 1997 after being together for 16 season; Bernstein had won 48 events and five championships with Armstrong.[3] Armstrong joined Don Prudhomme's Miller Lite team at the end of that season.[3] Larry Dixon drove Prudhomme's dragster on the first 4.4 second pass (4.486) at the Matco Tools SuperNationals. In 2000, Armstrong joined Jerry Toliver's World Wrestling team in Funny Car - the team led the Winston points in August before finishing third.[3]
Innovations
Armstrong became the first chief to test Funny Cars in a wind tunnel.[2] Other innovations included equipping dragsters with data recorders, installing a two-stage lockup-style clutch, and a fuel delivery system with two sources.[3] He developed dynamometer testing for nitromethane.[3] Some innovations later outlawed because they were too costly or too fast for the track included a three spark plug per cylinder magneto and a two-speed supercharger.[7]
Legacy
Armstrong was inducted into the Canadian Motorsport Hall of Fame in 1995.[1] He was named eleven times to Car Craft magazine's All-Star Drag Racing team;[7] he received their Ollie lifetime achievement award with Bernstein in 1997.[3] In 2001, the NHRA ranked him tenth on their Top Fifty drag racers of all time.[3] He was inducted into the Motorsports Hall of Fame of America in 2010.[8]
