Watched the Netflix Challenger documentary last night. Holy wow. If the engineers tell you we have this persistent problem the end result of which is catastrophic failure, and it's particularly bad during cold weather, and we strongly recommend you don't launch, then you don't bully the engineers into changing their minds.
It's not hard to see how group think got the better of them, but how many freaking times do people have to relearn this lesson!?!
And to think those astronauts and the teacher more than likely were conscious for the nearly three minute drop from 65K feet. Impossible to imagine, except to know that was a really, really long descent. That part's not in the documentary, but the evidence points to it.
