here's a quick and cool video of a shuttle night launch from kennedy space center.
Shuttle Launch: Cape Canaveral, March 11 from Seth Gadsden on Vimeo.
here's a much longer video from endeavor's launch last week (nov 14, 2008). its interesting to watch the last ~7 minutes before the launch and hear commentary explaining each move during the final stages of launch preparation! it would be so great to witness a night launch in person!
