Ok, here's some craft that nearly made the list:
Spinner - Police car from Blade Runner - Just about the coolest SkyCar seen on film
Star Destroyer - Star Wars - First you saw the Corellian Corvette, that was cool, then there was the ship following it, it went on......and on......and on......and on, then you saw the engines, I was blinded by its awesomeness.
X wing - Star Wars - Every little boy in 1977 wanted one (I preferred the y-wing for some strange reason)
Thunderbird 2 - Thunderbirds - another iconic Gerry Anderson creation
U.S.S. Cygnus - The Black Hole
