On January 28, 1986 despite the warnings of engineers not to launch in freezing temperatures, NASA management chose to launch Space Shuttle Challenger. The result was the loss of 7 astronauts in a horrific explosion 73 seconds later when flames from a solid rocket booster leak from a cracked o-ring and burned through the main fuel tank. The solid rocket boosters remained intact after the explosion and continued on out of control before mission control sent a self destruct signal to them so they could not cause destruction on the ground.

This video gives a detailed and technical explanation of the entire Challenger accident including pre-launch assembly, launch, post-launch, and accident investigation. It is highly recommended that the entire video be viewed to get a full understanding of the Space Shuttle Challenger accident.
