Empire State Building Fall

Two men are sitting drinking at a bar at the top of the Empire State Building when the first man turns to the other and says, "You know, last week I discovered that if you jump from the top of this building, by the time you fall to the 10th floor, the winds around the building are so intense that they carry you around the building and back into the window."

The bartender just shakes his head in disapproval while wiping the bar.

The second guy says, "What are you a nut? There is no way that could happen."

"No, it's true," said the first man, let me prove it to you." He gets up from the bar, jumps over the balcony, and plummets to the street below. When he passes the 10th floor, the high wind whips him around the building and back into the 10th floor window and he takes the elevator back up to the bar.

He met the second man, who looked quite astonished. "You know, I saw that with my own eyes, but that must have been a one time fluke."

"No, I'll prove it again," says the first man as he jumps. Again just as he is hurling toward the street, the 10th floor wind gently carries him around the building and into the window.

Once upstairs he urges his fellow drinker to try it. "Well, what the hey," the second guy says, "it works, I'll try it!" He jumps over the balcony plunges downward, passes the 11th, 10th, 9th, 8th floors ...and hits the sidewalk with a 'splat.'

Back upstairs the Bartender turns to the other drinker, saying "You know, Superman, sometimes you can be a real jerk."

Rufus Henry Gilbert

Died 10 Jul 1885 at age 53 (born 26 Jan 1832).U.S. surgeon and inventor who played a major role in the development of rapid transit in New York City. After serving as a surgeon in the Federal Army in the Civil War, he became interested in rapid transit as a means of freeing people from living in the unhealthful, crowded tenements in the centres of large cities. Gilbert obtained two patents in 1870 on a pneumatic-tube system, and he incorporated the Gilbert Electric Railway Company on 17 Jun 1872, to build elevated lines in New York City. The cars were to be propelled by air pressure from pneumatic tubes mounted on the elevated structure. A financial depression delayed construction until 1876, and forced adoption of a conventional track with trains drawn by steam locomotives, which opened 6 Jun 1878.
