Interesting. I'll have to see if I can catch that.

It sounds like a wing broke apart, probably due to heat.

There must be a normal wear and tear cycle to be reached with spacecraft. Even gun barrels, a relatively simple device, have to be replaced after a certain amount of firing. I can't imagine the level of stress the frame of the space shuttles must take over the course of a mission. To keep reusing it for a 25 year period seems utterly negligant.
