What a horrible way to wake up

I get up with thoughts no more complex than "coffee". My wife flips on the TV, and there it is - the shuttle Columbia apparently disintegrated on re-entry. It's a sign of the times that we live in that my first thoughts were whoa - sabotage. But that's probably not the case. Seven good people dead, and at the moment, no one knows why. With the size of the pieces being recovered, who knows if we'll ever figure it out.
