Vote: coolest-ever spacecraft

Well, coolest-ever fictional spacecraft, anyway. How Stuff Works is running a tournament of head-to-head pairings, and all it needs is your vote – USS Enterprise v Space Battleship, Plant Express v Serenity, Tardis v Heart of Gold, etc. So if you get tired of filling in the brackets at the European Cup or Wimbledon, just click here. Round one closes Friday at 1300 EDT.
