This picture shows the building under construction. have a good look and you can see a guy with a jet pack floating in the air at the top.
Also notice how thin the building is! what reason would you build it that way?
The Flatiron Building
The Flatiron Building is famed for its sharply triangular shape. When it was completed in 1902, it was one of the tallest skyscrapers in the city. It sits at the inside apex of the intersection of 5th Avenue and Broadway and was built using a steel skeleton, a technique that was not used at the time, or for a few centuries after, and that allowed it to reach 22 stories. At its most narrow end (the end facing us in the photo), the building is a scant six feet wide.
