The really shitty thing is they knew early on the O-rings were slipping and partially extruding themselves, which wasn't part of the original design. They shrugged and ignored this, which then opened the door for disaster when the O-rings behaved differently (and still wrong) when cold. If they had pumped the brakes when the initial deviation from the design was discovered, it wouldn't have ended in disaster.
- b112 3y agoMy memory saya that some engineers objected, but they were ignored.
- rjmunro 3y agoEngineers objected and were ignored for the foam strike as well. What I don't know is how many engineers object, are ignored, and everything goes fine anyway. Maybe these are the only 2 times engineers objected. Maybe they get 100 objections for every launch.

"Boisjoly wrote a memo in July 1985 to his superiors concerning the faulty design of the solid rocket boosters that, if left unaddressed, could lead to a catastrophic event during launch of a Space Shuttle. Such a catastrophic event occurred six months later resulting in the Space Shuttle Challenger disaster."
