The Challenger disaster led NASA to create an independent safety office

The Challenger disaster exposed flawed priorities in NASA's leadership

Reported issues with the shuttle's O-rings were deemed "acceptable risks" to proceed with the launch and ensure President Reagan could mention the success of Challenger in his State of the Union address. Postponing the launch would have also limited the publicity of educator Christa McAuliffe's live lesson from space.

The night before the disaster, not everyone signed the Challenger's launch authorization form

Allan McDonald, director of the booster rocket program at NASA contractor Morton Thiokol, refused to sign, believing ice on the spacecraft could damage the orbiter's heat tiles and that cold temperatures could cause O-ring failure. He later testified that management had overruled objections from engineers.
