The Challenger disaster was predicted the night before launch

On 27 January 1986, the night before the Space Shuttle Challenger launched, engineers at Morton Thiokol warned NASA that the O-ring seals in the solid rocket boosters were untested in the forecast 18°F temperatures. They recommended a launch delay. NASA managers overruled them under schedule pressure. Challenger broke apart 73 seconds into flight, killing all seven crew members. The Rogers Commission later found that NASA's organisational culture — specifically its tendency to normalise deviance — was as much to blame as the technical failure.
