Andre-Jacques Garnerinthe made the first parachute jump from a hot air balloon in France in 1793. Leonardo da Vinci had made detailed sketches of parachutes in 1485. He also sketched studies for a helicopter, a tank and retractable landing gear. The first helicopter that could carry a person was flown by Paul Cornu in 1907. Tanks were first used during World War One in Cambrai, France in 1917. The first airplane with retractable landing gear was built in 1933.
