I just checked - and voted, of course. Star Trek was in the lead with about 29%. Rush's Countdown was in 2nd place with about 23%.
Considering they wheeled the Shuttle Enterprise out to the Star Trek theme way back in the 70s, and the indirect affect Star Trek has had on the real space program, it would be only fitting to bookend the shuttle program with this music. Let's hope enough others feel the same way.
