@@keithparkhill8546 I'd say that depends on how you define political. Without Politics the space agency would have never happened to begin with. Politicians didn't care about the science of going to the Moon - they wanted to beat the Russians. Space Shuttle allowed scientific endeavors that would have never been possible without it, but again, the Reagan Administration didn't actually care about science. Reagan had some weird idea that the government would actually be turning a profit off commercialization of space using NASA. That has worked to some degree, as a private company that wants to launch a satellite will pay large sums to do so. But the sums paid to NASA to do such operations has never actually covered the cost. In a way it could be argued that tax dollars operating NASA have supplemented the capitalization of space. Of course there's nothing unusual about that. Most advances in technology happens because of governmental demands and endeavors.

Adding insult to injury: Allan McDonald and the other engineers thought that if Challenger did explode it would blow immediately upon ignition of the SRBs, right on the pad. When that didn't happen and she appeared to lift off normally, they breathed a sigh of relief thinking they'd dodged a bullet. Imagine the agony of seeing her explode a minute later.

[@imashaleyg]

I remember Roger saying he still expected it to blow he was just saying he thought it would happened right on the pad sooner but he was waiting for it cause he was checking the seconds on his watch or some whatever he said engineers used he said it was still going to blow regardless if it didn't happened right away.

[@michaelharnish3923]

It's really sad that this documentary almost eliminated the role of Roger Boisjoly. He was the Morton-Thiokol engineer who inspected recovered SRMs and had the data on the after-launch condition of the rocket O-rings. Mr. Boisjoly was the one who made the correlation between launch temperature and O-ring erosion, i.e., as the launch temp approached freezing there was more damage to the O-rings. He let his people at Morton-Thiokol know this in no uncertain terms. He went to the mat with it (he was a hot-head) because he knew he was right. This event was not an accident, but it was not intentional either. It was a preventable incident that was caused by NASA managers with "Go-fever" and Morton-Thiokol managers who gave-in to business pressure. Also eliminated from the soft news doc was the brilliance of Dr. Richard Fineman and his frozen O-ring demonstration at the hearings. Lesson: Listen to the engineers and heed the data.

[@PABadger13]

When you read the testimony, specifically the February 10 testimony, in the Rogers Commission Report, it doesn't quite play out the way the film implies. What he says to the Commission was: 1. There was a phone call on the 27th, which he was on. 2. On this phone call, Morton Thiokol made a no-fly recommendation based on blow-by data. 3. Morton Thiokol then reversed this recommendation after a short meeting taken off the phone call because NASA stated that the data were "inconclusive" (this is MacDonald's own word, and he states that the data *were* inconclusive). 4. MacDonald cannot explain the reversal of recommendation, as he was at Cape Kennedy, and not at Morton Thiokol, and states essentially that "you'd have to ask the people in that part of the meeting". Rogers himself cautions the commission that any testimony provided by MacDonald on what happened at the meeting anywhere but Cape Kennedy is hearsay. This is where Roger Boisjoly comes in. He was at Morton Thiokol ("Wasatch" in the testimony), and he could directly testify to what occurred on that end of the phone call. Further, he was able to testify directly to the Commission on the blow-by effects seen in testing.

[@charlesthomas8450]

There were two shuttle launches where blow by occurred in the joints during very warm temperatures on launch day. This is the argument that NASA gave Thiokol. This meant that Thiokol’s assessment of low temperature launches leading to O ring erosion was inconclusive. Thiokol had no argument in response.

[@imashaleyg]

Christa Mcaullife's backup and fellow teacher Barbara Morgan flew to the International Space Station in 2007 aboard Endeavour on STS 118. Notice how STS 118 had none of the publicity or recognition that STS 51 L had prior to launch. After Challenger, even after Columbia, NASA finally put a teacher in space. and almost no one knows about it. and in one of those moments that when you hear about it you think "that's how it should be", Barbara Morgan aboard the International Space Station taught children that had gathered at the Challenger Center for Space Science and Education. thus completing and honoring the mission of Christa Mcaullife .

[@jrockett73]

The reason it wasn't a big deal by the time she flew was because several other non astronauts had flown by then. Of course by the time Morgan flew she was a certified astronaut. On paper of course. She flew once and quit. She was a fish out of water and should have stayed in the class room.

It was completely the contrary. He took a cold hard look at the information from the previous low temperature launches and concluded that launching in even colder weather was heading towards a cliff even if they couldn't precicely predict at what temperature the cliff was. It was the managers that made a "gut" decision that since previous launches in cold weather had gone okay that there was enough redundancy build into the system that there wouldn't be a catastrophic event. Just a burned out O-ring or two and that was nothing to delay a mission over.

[@wombat2248]

His gut had nothing to do with it . His decision was based on the technical data , the performance of seals under cold conditions and other known factors as it should be . However he did have the balls to go against what must have been pressure from management . What I’d call a stand up guy . Nasa had grown slack , and caved under pressure to launch from the media , for their funding budget , the shuttle program ran massively over budget and behind schedule .

I remember thinking, after seeing the early pictures of the shuttle/rocket with ICICLES hanging off it, that it would be a very bad idea to launch. I just had an overwhelming feeling of trepidation about it. Sure enough, it was a disaster! And the aftermath, when all the "bigwigs" were trying to explain it away because of this or that, and Feynman asked a page to bring him a glass of ice water. He dropped a sample of the o-ring into the water for a few minutes, then pulled it out and SNAPPED it. All the bigwigs had nothing much to say after that. It was proven that this "accident" SHOULD NOT have happened. But because of their "shortsightedness" and arrogance, 7 people lost their lives that day.

[@theq4602]

Its not mentioned here. But one of the huge limits of the shuttle was from its booster's size. The diameter and the length of each segment was restricted by the railroad they used to transport them. There were four segments. They were built, fueled, and refurbished in Utah. This is why they had to assemble them as pieces in the first place. Thus why they had to use O-rings at all. A company called Aerojet had already built a much larger solid rocket motor that was taller heavier and more powerful than the shuttle SRBs, It didn't need to be put together and it arrived by barge as one piece. This would have negated the possibility of a Challenger altogether, No O-rings at all. No limits to the temperature they could launch at. It would have also increased the payload and range of the shuttle by a colossal amount. This motor was built in the mid 60's and called the "AJ-260" It is to date the most powerful rocket motor ever test fired. The reason they didn't use it or even consider it (it was offered in proposals by aerojet) was and still is because the boosters on the shuttle and now NASA's SLS were built in Utah by Thoikol. By coincidence Utah's senator heads the congressional comity over space budgets for NASA. This is one of his jobs as a senator for Utah. So you can guess who always kicked, screamed and bitched when anyone ever mentioned building shuttle boosters outside of Utah. Aerojet's boosters would have been built in Florida. They would have been superior to Thoikol's (now Orbital ATK) boosters in every single way.

@sykprop Thank you and the 3 others that responded to your post. I will add that a good manager knows both when and when not to override an engineering judgement. The military has overridden engineering decisions many thousands of times. However, those decisions were based upon recognition of the risks associated with both following the engineering assessment and not following that assessment. Sometimes, rarely outside of military actions, is the risk of following the engineering assessment recommendations greater than not doing so. But it does, and has happened. For a hypothetical example, suppose that astronauts on the space station were themselves in danger of dying if the shuttle did not launch when it was scheduled to launch. That risk could reasonably alter the decision matrix. That, of course, was NOT the sort of factor that resulted in the shuttle disaster! People like Al McDonald, Roger Boisjoly, and Arnie Thompson are indeed heros. These guys stuck to their conviction that a launch would endanger the shuttle crew (and indeed the whole program) even though they knew that they were risking their own careers!

As a kid when I went to the Kennedy Space Center in 1969, there had in recent history been a tragedy at the Space Center. The most poignant memorial was for the Apollo 1 astronauts Gus Grissom, Ed White and Roger Chaffee, who in 1967 were burned inside their capsule on the launch pad during a trial run. Later it was said the men suffocated to death first before burning, however, Roger Chaffee’s voice is heard on a tape saying “Flames!”. Ed White then said, “We’ve got a fire in the cockpit!”. Chaffee then yelled, “We have a bad fire!”. Then there was yelling until it went silent. The door could only be opened on the capsule inward and had latches that needed ratcheting open. Also cabin pressure held it closed and full venting had to be done before it could be opened. Well, the oxygen during the trial had permiated everything and allowed the flash fire. By the time it was opened, the three men had perished from smoke inhalation and burns..

I'm just imagining a nightmare scenario where all of the astronauts survived the breakup, and had the full 2 minutes before impact with the water to realize there was nothing they could do and had no possible way of surviving. We know at least 3 were conscious and thinking clearly enough to turn on their emergency air. God man, if they survived until the water impact then that would have been the most brutal last moments a person is capable of having. I can totally imagine how awful that would have been, Christy suddenly having the joy and wonder on her face turn to terror in a split second. Maybe she looked to the other crew members for some sort of instruction or escape protocol, only to see them as scared and confused as she was. From then, it would have been the most agonizing and hopeless feeling in the world, knowing you have a 0% chance of survival and are just waiting for the inevitable end... i'm really hoping they all lost consciousness within a half minute or so and didn't have to experience the nightmare plunge to their deaths. Evidence seems to show though that isn't the case unfortunately, and some if not all of the crew would have been awake and alert for a decent period of time following the explosion. The only way you could ever get me to travel into space like this would be if I could carry a handgun with me so that I could shoot myself and end it instantly if anything like this ever happened.

And we are talking about some of the most badass and well trained humans that ever existed here, which would have just made it that much worse for them knowing that despite the fact that they were as close to real life superhero's as a person could possibly get, it didn't mean a damn thing since a total breakup was never even considered, and therefore there was no contingency or escape plan to even give them a fighting chance. The only other scenario I can think of that even comes close in terms of the pure horror of the realization that not a single thing in the world is going to prevent your brutal death would be being trapped in one of the World Trade Center buildings above the point of the plane impact, and having to make the impossible decision between burning to death, or jumping and ending it right then and there.

This is certainly the best documentary concerning the disaster, just a shame that those named were never prosecuted in relation to the deaths of seven astronauts. How can anyone give their agreement to flight when their own engineers were telling them that it was not safe, and that a flight may well lead to disaster. If the engineers say it is not safe to launch, you don't go ahead and sign a bit of paper that says it is safe. It was not an accident.

[@EricCox4848]

+100SteveB A little thing called pressure from a government agency like NASA. Deadlines and commitments. Engineers knew a problem existed, but they were overruled by the higher-ups. No one saw the dangers of what they were doing until something like this happens. Astronauts knew the risks, but they didn't think about the danger and thought it was just another routine flight, except a civilian was among them. Some paid the price with their jobs or wound up reassigned within their organization.

This was my very first disaster I experienced as a young adult. I was very traumatized by it for many months if not years , and to this day, I still have that poster your see in the first few seconds of this documentary. I remember it like yesterday. I was pulling into a small mall listening to the pre launch chat on my car radio thinking , it’s amazing how we can do this sort of thing and their has never been an accident. By the time I got in the mall I was walking pass the then, Radio Shack and noticed many people gathered watching it on TV. I don’t remember anything after that day. But I remember I was so upset that I made a memorial at a print shop where I worked at a time to hang on my wall, of course, I was very young then. I think the most hurtful thing for me at the time was, that the very first civilian, a Teacher, was onboard and a lot of emphasis leading up to it was in the news all the time. Looking back, I think I was really proud and happy for her and I did not even know her. Then as I grew older, it seems one disaster after another came from Concord, Atlantis and in other areas around the world.

[@davewilkirson2320]

I remember the hoopla about Mr. McDonald standing his ground during his tenure on the failure team. I followed this event closely in 1986. I was a 28 year old engineer at Rockwell (Collins Radio) in Richardson, Texas the day the Challenger exploded (1-28-86). My team was notified, and we were asked to adjourn in the cafeteria that afternoon. Our VP was there and assured us the orbiter, of which was built by Rockwell's Space Division, was likely not the issue but rather the delivery system. Over the next few weeks, it was apparent that the evidence pointed to the SRBs and the cold weather and the rubber compound that made the O-Ring less likely to withstand the forces at work. The camera footage provided the compelling evidence during lift-off the primary O-Ring had leaked gas past the Tang joint. Most of us know that when a rubbery substance gets colder it will become more brittle to the basic understanding that molecules in that substance have slowed down and the effect could be degraded for what the substance was intended to do. No different than a good grade garden hose used in the summer heat to water your plants and then used in 20F weather to add water to your radiator. Basically, within a few days the disaster was determined to be a simple degradation of what the O-Ring was supposed to. I told my fellow EEs that and they agreed. NASA was on a timeline and failed to commit to what they were being told. The media drove NASA to some degree (same as today) and internal management made the mistake of being docile to the point of launching. Seven Brillant souls were lost. If commercialized space exploration continues (Elon Musk) there will always be failures. The systems are the most complex on Earth. Getting to space is difficult. Orbiting the Earth more difficult. Breaking orbit for a moon landing will eventually be commonplace and colonizing our closest (and only) satellite will not be easy. There will be lives lost NO DOUBT. Getting to another planet, such as Mars, will be a one-way event and those brave souls know this. Hopefully, a day will come when Mars cocolonization will be common. But not in our lifetimes. Elon Musk admitted lives will be lost.

I've always been angry about the disaster because it was completely unnecessary. Some people at the Kennedy Space Center knew about the problem with the O-Rings but let the launch proceed. One of the engineers even warned higher-ups, but they paid no attention and seven lives were needlessly snuffed out.

Hardesr thing for me was learning that it wasn't instant. That it was likely the water impact that killed them. Had me in tears hearing that.

On one hand, relief that it wasn't something he had made on the huge lathe he ran. On the other, feeling mad at himself for feeling that relief, when 7 people lost their lives that day.
