The Columbia Incident was the second space disaster, after Challenger. The launch went smoothly except for one thing, a piece of foam fell from the spacecraft. There's even video evidence of the foam falling. The spacecraft spent 16 days in space and then they decided to land it, However it went terribly wrong. The spacecraft broke during the landing and all 7 crew members died. It was all due to the foam and the hole in it's left wing it caused.
