Shuttle Challenger: Twenty Years Later

73 seconds into Shuttle Mission 51-L tragedy struck 20 years ago today when the Space Shuttle Challenger exploded killing her entire crew of seven, which included school teacher Sharon Christa McAuliffe, on the crew as Payload Specialist 2, but inaugurating the Teacher In Space Program (TISP).

Shuttle Mission 51-L had gone through a rocky 5 days previous to the launch at 11:38 on Tuesday morning (1:38am early Wednesday morning here in Japan) in 1986 with one delay after another culminating in a final 24-hour delay so a ground servicing equipment hatch closing fixture could be sawed off.
