The Empire State Building's spire was designed as a boarding dock for airships. Passengers would cross an open gangplank 1,250 feet above the street, then ride an elevator down. In September 1931, a small airship docked there for three minutes in 40 mph winds. Two weeks later, a blimp lowered newspapers to the tower on a 100 foot rope. Updrafts made the mast unusable. No airship ever truly docked there.
