In April 1914, after his wife's near fatal static line jump, Smith worked to improve parachute design. A patent, assigned to the Floyd Smith Aerial Equipment Company of San Diego, California, was filed on July 27, 1918 and issued May 18, 1920 for Smith's parachute. In September 1918, General Billy Mitchell directed that a team evaluate available parachutes and identify the best chute. Mitchell picked Glenn Martin test pilot and former flying circus daredevil Floyd Smith. Smith added motor mechanic Guy Ball to his two-man team. After the WWI Armistice, Smith's team came under command of Major E.L. Hoffman who added several other civilians including: Floyd Smith, Guy Ball, show-jumper Harry Eibe, Army parachutist Ralph Bottreil, engineers James Russell and Jimmy Higgins. The newly reorganized team tested 17 parachute designs including: static line designs of Broadwick, Stevens, Ors, Kiefer Kline, Otto Heinecke, Leslie Irvin, Omaha Tent Company, and Floyd Smith. The first tests, using dummies, favored Floyd Smith's parachute design. This winning design was further developed and merged key features into the "Type A" parachute: a soft pack worn on the back; a rip cord to deploy the parachute; and a spring-assisted pilot chute to aid in main parachute deployment. Conservative Major Hoffman and others believed the free-fall was dangerous and that a jumper might blackout before pulling the ripcord. Aerial circus jumpers Floyd Smith and Leslie Irvin convinced Hoffman to test the Type A with Irvin volunteering to jump and Smith piloting the test.
