Just saw news about the breakup of spaceshuttle Columbia. You forget that
this is very high risk activity. Very sad. The successes are taken for
granted until something like this happens. I feel for all thoe affected.

Initial speculation is that some of the tiles around or covering the
landing wheel wells may have failed, causing burn-through to the wheel
wells first; the last comm between the crew and ground control talked about
some problem with the tire pressure evident to the crew and also to ground
control. A few seconds later, telemetry appears to have been severed.
NASA will go up again -- the estimate for shuttle failures was one mission
in 75. They're about "on-track," though it's not a benchmark they want to
meet willingly.
