Allan McDonald refused to approve Challenger launch, exposed cover-up (2021)

Allan McDonald, the former director of the booster rocket project at NASA contractor Morton Thiokol, passed away at the age of 83. McDonald gained recognition for refusing to approve the launch of the space shuttle Challenger in 1986, which tragically exploded. He cited concerns about freezing temperatures, ice formation, and rough seas as reasons for a delay, ultimately prioritizing safety over potential career repercussions. McDonald's actions were considered heroic, both for his refusal to sign off on the launch and for later exposing a cover-up by NASA officials. Despite facing demotion initially, McDonald was eventually promoted and tasked with redesigning the booster rocket joints. He continued to advocate for ethical decision-making throughout his career and in retirement, leaving behind a legacy of integrity and principled leadership. McDonald's commitment to doing the right thing at the right time with the right people serves as a lasting example of ethical conduct in the face of adversity.

I wonder how often things like that happen.

The launch could have gone right, and no one would have known anything about the decision process besides a few insiders. I am sure that on project as complex and as risky as a Space Shuttle, there is always an engineer that is not satisfied with some aspect, for some valid reason. But at some point, one needs to launch the thing, despite the complains. How many projects luckily succeeded after a reckless decision?

In many accidents, we can point at an engineer who foreshadowed it, as it is the case here. Usually followed by blaming those who proceeded anyways. But these decision makers are in a difficult position. Saying "no" is easy and safe, but at some point, one needs to say "yes" and take risks, otherwise nothing would be done. So, whose "no" to ignore? Not Allan's apparently.

Allan McDonald is a new name for me. Thanks for posting this. See also other engineers who objected to the launch, like Bob Ebeling [0], who suffered with overwhelming guilt nearly until his death in 2016, and Roger Boisjoly [1], who never worked again as an engineer after Challenger.

This is an ever recurring theme in the human condition.

McDonald’s loyalty was not beholden to his bosses, or what society or the country wanted at that moment in time. He knew a certain truth, based on facts he was aware of, and stuck by them.

This is so refreshing in todays world, where almost everyone seems to be a slave to some kind of groupthink, at least in public.

There’s a good lecture about this, called “The Normalization of Deviance”:

What we should remember about Al McDonald [is] he would often stress his laws of the seven R's," Maier says. "It was always, always do the right thing for the right reason at the right time with the right people. [And] you will have no regrets for the rest of your life.

"Truth, Lies, and O-Rings" is a fascinating (if sometimes tedious) book that should be at the top of any reading list for those interested in the Challenger disaster.

For me one of the more interesting side-bar discussions are those around deciding to use horizontal testing of the boosters despite that not being an operational configuration. This resulted in flexing of the joints that was not at all similar to the flight configuration and hindered identification of the weaknesses of the original "field joint" design.

It's also worth noting how the o-ring story was made public. There is the famous testimony by Richard Feynman[0], but the secret was that astronaut/commissioner Sally Ride leaked the story to another commissioner, who then suggested it to Feynman over dinner[1].

Neither Ride nor Kutyna could risk exposing the information themselves, but no would could question or impeach Feynman.

It's a shame we don't have more engineers today that refuse to invent things because so many technological inventions today are being used to further the destruction of our planet through consumerism.

Sadly, human society has a blind spot when it comes to inventions with short-term benefits but long-term detriments.

I would love to see more programmers refusing to work on AI.

I have an unclarity with this situation.

How much of him being a hero is a coincidence? Did he refuse to sign the previous launches? Did NASA have reasons to believe that the launch could be successful? How much of a role does probability play here. I mean if someone literally tells you something isn't safe, especially the person who made it, you can't tell him it will work. There is somekind of bias here.

> He neglected to say that the approval came only after Thiokol executives, under intense pressure from NASA officials, overruled the engineers.

Sounds kinda familiar?

I got to eat lunch with Allan Macdonald in college. I was an IEEE officer and we hosted him for a talk at Montana State, so I got to take him out for lunch before his talk.

Dude got a lunch beer without a second though. (My man!)

He then gave a talk that afternoon talking about interrupting a closed session of the Challenger commission to gainsay a Thiokol VP. The VP in question testified to Congress that he wasn't aware of any launch risks. Macdonald stood up, went to the aisle, and said something to the effect of "Mr. Yeager, that is not true - this man was informed of the risks multiple times before the launch. I was the one that told him." (He was addressing Chuck Yeager, btw. Yeah, that Chuck Yeager.)

No mean feat to have the stones to interrupt a congressional hearing stacked with America's aviation and space heavyweights.

It's sad to see the decline of civilization, and how far back basic principles were not understood, and turned into a cargo cult. The point why somebody had to sign something to approve it was exactly that he had the option to not sign it in case that there was a problem. But even then, it was seen as a job to be done, that you either do, or fail to do.

McDonald was my hero as a young engineering student. The miracle was that he was exonerated.

What is missing here for me is who were the anonymous "executives" that overruled Mcdonald (and others) and tried to punish him? Did they suffer any consequences for actions that cost lives and for the coverup?

Rest in peace Allan.

As much as his action were admirable, the most shocking thing about that story was how the politicians rallied to protect him after his demotion, forcing his company to keep and actually promote him. That's why I get both sad and angry when I hear the new mantra of "Government can't do anything, the markets have to regulate that problem."

> Allan McDonald leaves behind his wife, Linda, and four children — and a legacy of doing the right things at the right times with the right people.

It sounds like the most noteworthy part of his legacy is attempting to do the right thing, but with the wrong people.

I think this is meaningful to mention, because saying to do "the right things, at the right time, with the right people" is easy -- but harder is figuring out what that really means, and how do you achieve that state when you have incomplete control?

Now that OSS projects like a certain popular dynamic language have been taken over by corporations, criticism like security or performance issues are forbidden as well and punished.

(One corporation though seems to withdraw from that language due to the attitude of the project and its representatives.)

I'm late to the party, but I work as a NASA contractor and have just recently been reading "Truth, Lies, and O-Rings" by Mr. McDonald.

Something that I find really frustrating is that it seems that there's an international "caste" of honest engineers who are ready, and have been ready for centuries if not millenia, to pull the metaphorical trigger on advancing human society to the next level. International rail systems, replacing all electrical generation with nuclear, creating safe and well-inspected commercial airplanes, etc.

Blocking that "caste" from uniting with each other and coordinating these projects are the Old Guard; the "local area warlords", although these days they may have different titles than they would have a thousand years ago. These people do not speak a language of technical accuracy, but rather their primary guiding principles are personal loyalty, as was common in old honor societies. They introduce graft, violence, corruption, dishonesty, and personal asset capture into these projects and keep them from coming to fruition. They would not sacrifice their lifestyles in order to introduce technical excellence into the system they're charged with managing, but instead think more about their workload, their salary, their personal obligations to their other (often dishonest) friends, and their career tracks.

It wouldn't even occur to me to worry more about a promotion than than the technical merit of a machine or system I was engaged with. I would never lie about something myself a colleague of mine said or did. For those reasons I will never be particularly competitive with the people who do become VPs and executive managers.

How many different people around the world, and especially that are on HackerNews, are in my exact situation? With the right funding and leadership could all quit our stupid fucking jobs building adtech or joining customer databases together or generating glorified Excel spreadsheets and instead be the International Railway Corps, or the International Nuclear Corps. And yet since we can't generate the cashflow necessary to satisfy the Local Area Warlords that own all the tooling facilities and the markets and the land, it will never be.

> at some point, one needs to say "yes" and take risks

Sure, but they need to understand the risks, and be open about the choices they are making. Ideally at the time but certainly coving it up after it goes wrong is not acceptable.

And then all of their government contracts should have been revoked.

Ok, cool, but what the hell happened? They had a guy in charge of signing-off the launch, he didn't sign off because of 3 problems he identified, and they still launched. wtf?

> McDonald became a fierce advocate of ethical decision-making

My hero, but also Don Quixote. I'm a huge believer in Personal Integrity and Ethics, but I am painfully aware that this makes me a fairly hated minority (basically, people believe that I'm a stuck-up prig), especially in this crowd.

I was fortunate to find an employer that also believed in these values. They had many other faults, but deficient institutional Integrity was not one of them.

I don't relish all of the issues which will eventually surface with SpaceX's Starship, which makes Space Shuttle development look like a paragon of high quality development practices. Starship is built in a metaphorical barn with a "fuck around and find out" attitude.
