they certainly don't take anything lightly when it comes to debris coming off the vehicle. that's what, as we know, caused the "columbia's" disaster when the leading wing was damaged by foam coming off of the external tank. they will take a critical look at this. and you know, wolf, they have the capabilities now since t "columbia's" accident to go outside and take a spacewalk, and if there's a damaged tile, they can put a astronaut on the end of a robotic arm and literally repair those tiles. we'll be listens to the post-launch news conference. other than that, wolf, picture-perfect launch, they're on their way to a rendezvous with the space station, and at first blush, this does not appear to be too too serious. as one of the officials told me if it happened within the first minute of launch, that would be a bit more of a concern.
