Does the empire state building have 81 floors?

It has 102, but only the first 85 are used as office space, and the 86th is a observation deck. The last 16 stories are the Art Deco tower, which is capped by a 102nd-floor observatory. Although the ticket you receive says 102nd Floor, you are actually taken to the 101st floor. The 102nd floor was designed to unload passengers from dirigibles (blimps) that moored to the building -- an idea that was quickly declared unsafe because of high winds.
