The “Mobile Control” procedure that you’re referring to was developed by the 4070th Support Wing of Strategic Air Command headed by Colonel Yancey. He was tasked in 1955 with developing the training programme for U-2 instructors and operational CIA and USAF pilots. The first six IPs qualified in late 1955, and the first (CIA) course started training in January 1956.
However, it’s not that simple. Once operational, the CIA dispensed with the system for experienced pilots. In the ‘50s and ‘60s the USAF employed it at SAC bases (Laughlin, Davis-Monthan, Barksdale), but it was not always used when detached.
