Chapter 2
U-2 detachment in formation over Nevada
Colonel Yancey's group carefully examined all aspects of the U-2 unit from flight crews to camera technicians and mission programmers. When the exercise was over, Yancey reported that the detachment was ready for deployment. He then briefed a high-level Pentagon panel that included the Secretary of the Air Force and the Chief of Air Staff. These officials concurred with Yancey's determination that the U-2 was ready for deployment. $ ^{57} $
During these final tests in the spring of 1956, the U-2 once again demonstrated its unique airworthiness. On 14 April 1956, James Cunningham was sitting in his office in Washington when he received a call from Area 51 informing him that a westward-bound U-2 had experienced a flameout over the Mississippi River at the western border of Tennessee. After restarting his engine, the pilot reported a second flameout and engine vibrations so violent that he was unable to get the power plant to start again. Early in the program Bissell and Ritland had foreseen such an emergency and, with the cooperation of the Air Force, had arranged for sealed orders to be delivered to every airbase in the continental United States giving instructions about what to do if a U-2 needed to make an emergency landing.
Cunningham had the project office ask the pilot how far he could glide so they could determine which SAC base should be alerted. The pilot, who by this time was over Arkansas, radioed back that, given the prevailing winds and the U-2's 21:1 glide ratio, he thought he could reach Albuquerque, New Mexico. Within minutes Cunningham was on the phone to Colonel Geary in the Pentagon, who then had the Air Force's Assistant Director of Operations, Brig. Gen. Ralph E. Not linked to a story yet.
