This is SO sad!!

Oh my God! just last night while watching the news, they were talking about the shuttle and that if we looked up at 8:02a (our time), we would see the shuttle passing over the city. At 8:05a, we would be able to hear a sonic boom. For real, I am really tripping out over this!
Hasn't this flight been put off before because of problems with the shuttle? Is it possible that there are any survivors?
EDITED:
I just got news from CNN that "the shuttle is 'gone'." That being said, I guess my question about survivors has been answered....
