Sorry to disappoint Trekkies who still believe, but the actual USS Enterprise did not really take up much space.
That famous starship of Mr. Spock and Capt. James Tiberius Kirk in the original Star Trek TV series — which turns 50 this year — was a model. Quite a large one, to be fair: 11 feet long and about 200 lbs., made out of blow-molded plastic and wood. But not life-sized.
And for more than a decade, it hung in the gift shop of the Smithsonian's National Air and Space museum in Washington, D.C.
