Lol! And to think that was once a serious idea! To have people access blimps via the Empire State Building!
From Wiki:
Dirigible (airship) terminal
The building’s distinctive Art Deco spire was originally designed to be a mooring mast and depot for dirigibles. The 102nd floor was originally a landing platform with a dirigible gangplank.[28] A particular elevator, traveling between the 86th and 102nd floors, was supposed to transport passengers after they checked in at the observation deck on the 86th floor. However, the idea proved to be impractical and dangerous after a few attempts with airships, due to the powerful updrafts caused by the size of the building itself.[29] A large broadcast tower was added to the top of the spire in 1953.[28]
