Stuff hangin' off the shuttle

Anybody else worried that we are going to have another catastrophic failure of the Space Shuttle? I felt a little better when the space walk to repair strips of filler hanging off the tiled underside of the ship went without a hitch, but I'm still a little shaky. The Columbia and Challenger explosions are still fresh enough in my mind to keep me that way. These are truly brave women and men that risk their lives to conquer space. Good luck to them. Patsy and Aurthur will keep an eye out for you!
