Spread your wings and soar

If the word wingsuit does not ring any bells, how about the Transformers 3 scene of men flying between skyscrapers in Chicago like flying squirrels?

A wingsuit, also known as a birdman suit or bat suit, adds surface area to the body and increases lift. Most wingsuit designs create a surface area between the legs and under the arms.

There are about 600 wingsuiters around the world. They wear parachute equipment designed for skydiving, or BASE jumping, which stands for Building, Antenna, Span (bridges) and Earth (cliffs) - all objects to jump from at high altitudes.
