1. Managers telling engineers how to do their jobs. Could not get worse than that.
2. Gut-Wrenching to see and hear her enthusiasm 7:25
3. So typical
4. Larry Mulloy was one of those at NASA management directly responsible for the death of those astronauts. Why is he being interviewed? He should stay crawled under a rock that he has been hiding under all these years and disappear from the conscience of the public forever. NASA managers were asking Morton Thiokol engineers Roger Boisjoly and Allan McDonald to prove that the O rings would fail at any given temperature. That is like asking someone to prove that by jumping off of a cliff that you would break your legs or even die. Doesn't matter that other people have died in the past doing that, but you must prove that YOU when jumping off a cliff will die or be badly injured. The only way to prove it is by jumping off. How do you deal with such idiotic demand? The only proof they had was evidence from previous cold weather launches where there was significant burn-through of O rings and only pure luck kept those incidents from becoming disastrous. But the luck ran out on January 28th, 1986. Ronald Reagan's SOTU address that same night didn't help in this regard either; NASA was under tremendous pressure to launch that day with the teacher in space program, Reagan's pet project.
5. "continually fell behind..." Kinda sounds like a particular young Space Rocket company.
6. Kalpana was SO beautiful...so very sad.
7. I will be showing this tomorrow in my Organizational Behavior class tomorrow at the American University in the Emirates (in Dubai, UAE). I will then ask my students five questions about the culture of NASA and how poor decision making resulted in the death of the Challenger astronauts (and later the Columbia astronauts). 30 years later and this still makes me get teary-eyed. Thank you for this thoughtful and thorough documentary that is the perfect length!
8. The Columbia was the very first space shuttle. It really could/should have been saved and would have been part of history today. More important, the lives could have been saved if they had learned from their Challenger mistakes. (And how sad is it to hear the narrator say "NASA pays the Russian Space Agency to carry American Astronauts into space."
9. They really should have learned from the Challenger, but made the same mistake not listening to warning signs with the Columbia
10. 30 years later now 😰😰😰😰😰😰😰😰😰😰
11. Should be called, "How NASA failed itself!"
12. hhhhaa now this is comedy
13. they were not able to go in space in 1980s, how it was possible to reach on moon in 1950s ?
14. seven astronauts were thrown directly to hell from space.
15. Watching the beginning of this it's so unsettling, since you know what's going to happen.  I was so tense up until the explosion, just waiting.
16. Thanks for uploading this - The story of challenger and this video are a textbook case of engineering safety and workplace ethics.
17. I have never cried so much during a Retro Report. I cried three times during this. That opening was so terribly sad. The people who accept pressure to ignore life threatening data not only in these missions, but other everyday situations...why can we, as humans, not take that extra moment to consider things? The extra moment that could save lives? That extra moment to stop a disaster? Those poor people who died, and those poor people responsible. Nobody wins in times like this.
18. I feel sorry for them........... I never had idea of this.
19. Does anyone know the music at 9:40?
20. The price for human curiosity.
