Columbia, the second space shuttle disaster was a major US tragedy.
Investigation showed during launch debris fell onto and damaged heat-shielding tiles on the front edge of the left wing.
Damaged tile allowed hot gas to enter the wing upon reentry into earth's atmosphere, gradually burning up components, which led to the disintegration of the shuttle.
For many people, perhaps most, that is all they want to know.
Others, like myself, are geeks very interested in understanding the why of technical things.
Below's a 14-minute real-time 'documentary' someone assembled for the curious.
It shows a graphic of systems and sensors in the left wing.
The sensors are all green before the craft enters the earth's atmosphere (friction with which generates the intense heat).
One by one the color of sensors' changes as each heats up and eventually fails, then goes offline, and turns blue.
Watch it, or don't.
