This isn't what I really thought I'd wake up to this morning. It is really terrible, and quite a shock.
I've always been a space buff, right back to my earliest memories. I remember the Challenger disaster quite vividly - I was in high school at the time.
There is plenty of speculation as to what caused it, but it may have to to with some damage to the left wing on take off from a piece of insulation from the center tank.
Astronauts have always been heros to me, and its really terrible to see this.

They lost temperature information on the left wing, the loss of temperature data and then loss of tire pressure data just before the loss of contact.

From the breakdown of the information that NASA has given out it appears to *me* that the damage sustained to the left wing on launch probably was more serious than was first thought. Upon re-entry, the left wing's damage allowed heat into the frame of the wing, eventually taking it off, and then making the orbiter tumble until it broke apart.
At the velocity and heat levels involved I don't expect that the astronauts felt very much. That much is fortunate, rather than what some of the astronauts on Challenger experienced.
A terrible day indeed.
