It shook the house, rattled the windows and scared the hell out of my 16 pound guard dog! I Immediately looked at the clock and it was 10:11 pm. Upon changing the TV channel and hearing that the shuttle was making a final night-time approach, and scheduled to land at 10:14....I realized it was the SONIC BOOM that we just heard. Imagine .....going across the state of Florida in 2 or 3 minutes!
