The story of how engineers working for a NASA subcontractor tried desperately to prevent the ill-fated final launch of the Challenger shuttle. The engineers believed that rubber o-rings, critical components of the solid-fuel booster rockets, would likely fail at the very low temperatures forecast for the launch. However, management overruled them and the fatal launch went ahead. A Congressional enquiry later exposed the truth, assisted by one of its members, a Nobel prize-winning scientist.
The crux of the whistleblower story is in parts 6 & 7, where the engineers make their case and are overruled. The public was subsequently outraged to learn that reprisals were taken against the engineers after they testified to Congress, and this led to the first US whistleblower protection legislation.
