Currently home to the Terrace on the Park banquet hall in Flushing Meadows-Corona Park, this building originally served as a heliport for the 1964-65 World’s Fair. It stood in the Transportation Area of the fair, with each side of the structure forming a big T, for "transportation". During the fair in 1965, the Beatles landed here en route to their legendary concert at Shea Stadium.
(In the background at right, peeking over the trees, you can see the tallest observation tower of the World's Fair's New York State Pavilion.)
Could also be part of a set from “The Thunderbirds”
