parachute
There were parachutes invented before Leonardo's time but he improved on it the most. The parachute that he designed was roughly seven and two tenths long and high. It was made out of wooden poles and a cloth of linen. There is no hole at the top of this parachute so it would not balance as well as parachutes today. the Parachute was tested on June of 2000 and was a susses. Although parachute mostly fall under the category of flight, parachutes are used in the military today. Leonardo did not mean to make parachutes for the military.
