Robert Boisjoly Dies At 73, the Engineer Who Tried To Stop the Challenger Launch

demachina writes "Robert Boisjoly has died at the age of 73. Boisjoly, Allan J. McDonald and three others argued through the night of 27 January, 1986 to stop the following day's Challenger launch, but Joseph Kilminster, their boss at Morton Thiokol, overruled them. NASA managers didn't listen to the engineers. Both Boisjoly and McDonald were blackballed for speaking out. NASA's mismanagement 'is not going to stop until somebody gets sent to hard rock hotel,' Boisjoly said after the 2003 Columbia disaster. 'I don't care how many commissions you have. These guys have a way of numbing their brains. They have destroyed $5 billion worth of hardware and 14 lives because of their nonsense.'"

A prize nomination?

[samjam]

Perhaps he should be nominated for the not-yet existing Bradley Manning prize for integrity in the face of overwhelming odds.

Re:A prize nomination?

[Rotag_FU]

While not a prize, he is someone who has been effectively immortalized in engineering ethics classes, at least in the US. The Challenger incident, and his participation of it, are studied in some depth right alongside the Tacoma Narrows and Quebec River Bridge incidents. Admittedly I speak from a relatively small sample size (direct personal experience plus anecdotal evidence from ~10 other engineering colleagues), but the samples are from geographically diverse schools in the US. I'm curious if this case is studied in engineering ethics classes abroad?

I'm actually burning mod points that I used because I just have to point out that, I have a Bachelor's of Science in Business with a focus in Management (long title for BS of Management degree), and this topic and topics like it never came up. Not once. Not ever. This is more than a, "gleaming nugget of pure gold," as Rogerborg put it, it's a solid bar of it.

Management (myself included to a mild extent, that extent might be why I'm so low on the management totem pole) is far too often worried about getting the numbers right or getting things done for the sake of getting them done instead of getting them done well, right, safely, or not getting them done at all if any of these aren't and can't be the case. I am striving to make sure that, when my employees tell me we will not get this done in time unless we cheat the numbers, I tell them, okay, let's see if we can get as much help as we need for this (again, low on the totem pole). I'm of the mindset that a job should be done right rather than just done. Shame it seems I'm the only one within my company.

> 17 lives lost in the last 50 years of U.S. space exploration really is not too bad

Understand your reasoning but that's not the point here. Those lives and money were lost due to human negligence and pure bullheadedness. The loss was easily preventable.

Re:In perspective

[FunPika]

Still, this guy should have been taken somewhat seriously. He had over 20 years of experience, had been working at the company that developed the SRB's for several years, and was ignored even after showing his managers photographic evidence of damage being caused to the O-rings by cold weather with several of his colleagues on the team agreeing.

NASA not any different today

[HangingChad]

Both Boisjoly and McDonald were blackballed for speaking out.

I think that's the bigger issue here. NASA really hasn't changed, they're the same arrogant, top heavy, risk adverse organization they bloated into during the 80's. You'd think they would have been humbled by seeing heavy lift moved over to the Russians, but it hasn't dented their attitude one bit.

It's not the lives that were lost, it was the circumstances surrounding the loss and the general lack of accountability afterwards. Engineers who try to sound warnings still will get blackballed. Nothing really changes when you have the problem dictating the solution.

Re:In perspective

[Hijacked Public]

Not really, because regardless of their false positive rate the evidence is what the evidence is.

Actually what you need is an eyes-wide-open, honest evaluation of the data, that isn't tainted by the interests of NASA or its subs or politicians who are have taken some positionon matters related to the above. And good luck with that.

If you read much Edward Tufte or attend one of his talks, he has a lot to say about the decision making processes for both the Challenger and Columbia incidents. I am dubious that an entire army of actual rocket scientists could have, of their own accord, made multiple data presentation choices that cast their employers in the best possible light. Laying out a graph that eventually helped a room full of smart people decide that the booster seals would be fine on the launch date. When those same data plotted differently showed an obvious direct correlation between failure and ambient temp and they were going to launch on the coldest day yet.

There is similar manipulating of the data from the Columbia.

People trying to serve some incidental interest, like preserving a contract or future funding, who are obviously cherry picking the information they share, aren't likely to be swayed by a low false positive rate. They made their decision long before they saw any evidence of anything anyway.

Problem Recognized EARLIER by Rudolph Krueger...

[BoRegardless]

When the bids went out to professional engineers in the aerospace seal business, my friend, now gone sadly, was asked to bid on the large O'Ring seal design for the shuttle booster rockets.

He did his basic expansion calculations on what temperature changes would do to the large diameter structure and came to the conclusion it would not work and replied declining to quote with a note that it didn't seem to be workable because of basic physics.

Rudolph's opinion was never seriously taken and we know the result.

A few words for the man

[A10Mechanic]

I prefer to remember him as the cool guest lecturer and advisor we had at Weber State for the NUSAT program. Keen intellect, razor sharp, and driven. There's more to the man than just Challenger.

Not one more funeral

[plopez]

I was working for a large, not directly tech related (though they do some research) Federal Agency last year and the word came down that the "Chief" (the highest ranking civil servant, not appointee) was unwilling to kill more people. We had a work stoppage, training classes etc. And the attitude of "Well, adjusted for man-hours of work we kill fewer people than other agencies." was unacceptable. He claimed he was tired of flying out fro D.C to attend funerals.

So we did training classes and any employee is now supposed to be able to cry "Stop!" when something starts to get too hazardous without consequences. During the classes employees who tried to use the argument "Well, adjusted for man-hours of work we kill fewer people than other agencies." were "hammered" for missing the point. *The point is a culture of safety where one loss is unacceptable.*

I find that sane and sensible.

Will it work? Who knows. It will probably take a few years to find out.

He spoke at my elementary school when I was in 4th

[Pezbian]

When I was in 4th Grade, I had the good fortune to meet Boisjoly and a couple of other engineers from Thiokol. It wasn't like meeting a national celebrity or anything because I grew up in Brigham City, Utah, which is close enough to Thiokol that you can see the smoke plumes from booster tests rise up over the western mountains.

At my school, a group of fellow students and I had the opportunity to hold a demo model o-ring just like the ones used to join the booster segments. These demo units were just the ones that didn't pass muster for actual use. The group and I held one o-ring spread out in a full circle and nearly covered the entire floor of the classroom. They're huge and didn't feel like the household o-rings I was used to. I could definitely see something like that getting stiff or brittle at low temperatures. My memory is hazy, but I'd almost compare it to a Neoprene type feel.

I mentioned Challenger and how I learned about the o-rings (my grandpa, who also got me started in Electronics, told me about it). The engineers seemed surprised that a ten year old kid would know, let alone care, about that kind of thing.

Among the other visual aids the engineers brought, there was a piece of spongy SRB fuel with a couple of ingredients missing so as to make it inert. It was Boisjoly who calmed me down after I was angry with myself for breaking the piece in half while checking the flexibility of the material to see just how sponge-like it was.

For years after that, while still living in Brigham City, I got to see booster segments passing through town (can't take the freeway) on the way to Thiokol (now ATK) on the back of massive semi trailers with police escorts and utility workers leading the pack with tall poles on the front of their work trucks to make sure the lines over the roads would physically clear the booster and then holding the wires out of the way if there wasn't enough clearance. I always thought back to holding that o-ring and how truly massive it was.

I only ever saw one booster test and that was back in 2003. The dead-silence for the first few seconds (speed of sound, you know?) is eerie. After that, even from over a mile away, the noise hits you like a freight train. Those o-rings are charged with holding back a truly ridiculous amount of force.
