I live in East Texas and the shuttle exploded over us. I was asleep but my "hard of hearing" spouse heard the explosion and said "It had a percussion to it" (spouse finally gave in and got hearing aides just a few weeks ago - hearing confirmed not good) My parents heard it too, said it rattled the windows of their house.
Additionally, debris was found allover the area. A long time employee of my spouse reported that he found a partial foot with polish on the nail.
