On 28 April 1919 using the "Type A" 28 foot backpack parachute, volunteer Leslie Irvin, flying in a Smith piloted de Havilland DH9 biplane at 100 mph and 1500 feet above the ground, jumped (with a backup chute strapped to his chest) and manually pulled the ripcord fully deploying his chute at 1000 feet. Irvin became the first American to jump from an airplane and manually open a parachute in midair. The new chute performed flawlessly, though Irvin broke his ankle on landing. Floyd Smith filed the Type A patent No. 1,462,456 on the same day. The McCook Field team tested the Type A parachute with over 1000 jumps. These successful tests resulted in the Army requiring parachute use on all Air Service flights.
