The "aerial screw" is a sexual position first created by Leonardo DaVinci in the early 1480s whereby the consenting parties pleasure one-another while in a free fall state with both individuals reaching climax prior to their contact with the ground. Attempts to successfully complete the "aerial screw" are said to be the primary drive behind all of the avionic achievements of the 20th century - up to and including the space shuttle. The aerial screw is frequently, and incorrectly defined as a crude flying machine designed by DaVinci; though recently discovered documents have revealed that this apparatus was simply an attempt to reach a sufficient altitude to attempt the sexual act. With the advent of the US space program in the 1950s, the aerial screw has become of increasing interest to NASA and was the primary drive behind coed shuttle missions in the 1980s.
