I guess they are possibly more fragile, but the bottom tiles experience much higher temperatures than the top surfaces. I guess that we know that even with some of the bottom tiles missing, the orbiter doesn't suffer too much damage, so I guess that turning the bottom to the burn makes sense, but it doesn't seem to be clearly the obvious thing to do. marcus hall
