ParachuteIn 1919, the first jump with the Army manually operated army parachute was made by Leslie LeRoy Irvin in Dayton, Ohio. This was the first test of this type, known as the "free parachute," with which the operator jumps before pulling the ripcord. He jumped at an altitude of 1,500-ft from a de Havilland DH-9 biplane while flying at 100-mph over McCook Field, Dayton, Ohio. He broke his ankle upon landing on the ground. Later, he founded the Irving Air Chute, Co., which business name resulted from an spelling error on the incorporation papers. |
