Evolution of Parachutes

	1. Leonardo Da Vinci Codex Atlanticus Folio 381 "If a man have a tent of linen without any apertures, twelve ells across and twelve in depth, he can throw himself down from any great height without injury" Cod. Atl., fol. 381 v-a
2. The basic round parachute design did not change appreciably for almost half a century.
	3. Bernoulli's principle was applied to the parachute design, stabilizing it and slowing the rate of descent. A version is still used in schools today.
4. Pierre Lemoigne, a French engineer designed this improved parachute named the Para-Commander in America. This parachute won almost every competition for the better part of a decade.
	5. The 1966 Barish Sailwing was the forerunner of today's high performance parachutes.
6. In the mid 1970's, the high performance rectangular parachutes commonly called "squares" replaced circular models in competition.
