Nacogdoches, Texas-AP -- The call to 9-1-1 described something "very strange" in the skies over east Texas last Saturday morning.
The emergency call was among the first to describe the break-up of the space shuttle "Columbia."
That eyewitness wondered if a plane had just blown up.
But another caller -- an experienced shuttle watcher -- knew all too well.
She reported in a shaking voice that she had probably just seen the space shuttle explode.
But, as she told the dispatcher, "I know there's nothing you can do."
