Update: Janet Smith-Bozart, who was driving near Dallas, saw what is believed to be the shuttle?s descent and described it to MSNBC. ?I thought at first it might be a meteor coming into the atmosphere and then I realized it was much too big and much too slow for that,? she said. ?Essentially the entire thing just broke apart and the whole thing just disappeared. ... Eventually it just sort of faded and there was no more contrail or anything.?Explosions were widely reported across Texas.?It was like a car hitting the house or an explosion. It shook that much,? John Ferolito, 60, of Carrolton, north of Dallas, told the Associated Press. (MSNBC)
