of its propensity to go into an unrecoverable spin in the mountainous terrain. In early April the Air Corps removed all pilots with less than two years' experience from the operation. The Air Corps began drawing down AACMO on May 8, 1934, when temporary contracts with private carriers were put into effect. On AACMO's last night of coast-to-coast service on May 7–8, YB-10s were used on four of the six legs from Oakland, California, to Newark to match Rickenbacker and Frye's DC-1 stunt, flying a greater number of miles and making three extra stops in just an hour's more time. Only two additional Army pilots were killed flying the mail after the resumption of operations, on March 30 and April 5. By May 17 all but one mail route, CAM 9 (Chicago to Fargo, North Dakota), had been restored to civil carriers. AACMO relinquished this last route on June 1, 1934. Results In all, 66 major accidents, ten of them with fatalities, resulted in 13 crew deaths, creating an intense public furor. Only five of the 13 deaths actually occurred on flights carrying mail, but directly and indirectly the air mail operation caused accidental crash deaths in the Air Corps to rise by 15% to 54 in 1934, compared to 46 in 1933 and 47 in 1935. In 78 days of operations and over 13,000 hours of logged flight time, completing 65.8 percent of their scheduled flights, the Army Air Corps moved 777,389 pounds of mail over . Aircraft employed in carrying the mail were the Curtiss B-2 Condor, Keystone B-4, Keystone B-6, Douglas Y1B-7 and YB-10 bombers; the Boeing P-12 and P-6E fighters; the Curtiss A-12 Shrike; Bellanca C-27C transport; and the Thomas-Morse O-19, Douglas O-25C, O-39, and two models of Douglas O-38 observation aircraft. Among the 262 Army pilots flying the mail were Ira C. Eaker, Frank A. Armstrong, Elwood R. Quesada, Robert L. Scott, Robert F. Travis, Harold H. George, Beirne Lay Jr., Curtis E. LeMay, and John Waldron Egan, all of whom would play important roles in air operations during the Second World War. Consequences and effects Effects on the airline industry The government had little choice but to return service to the commercial airlines, but did so with several new conditions. The Air Mail Act of June 12, 1934, drafted at the height of the crisis by Black (and known as the "Black-McKellar bill"), restored
