This is a 1992 CIA History Staff monograph by Gregory W. Pedlow and Donald E. Welzenbach, originally classified Secret NOFORN and approved for release in 2013. It covers the CIA's manned overhead reconnaissance program from 1954 to 1974 and the two aircraft it developed, the U-2 and the A-12 OXCART. The history covers the U-2 overflights of the Soviet Union, the 1960 downing of Francis Gary Powers and later operations in Asia and Latin America. It also includes a section on U-2s, UFOs and Operation BLUE BOOK.

(USAF, Ret.), a vice president of the Shell Oil Company who had long been involved in overhead reconnaissance (most recently as a member of the Technological Capabilities Panel), arranged for Shell to develop a special low-volatility, low-vapor-pressure kerosene fuel for the craft. The result was a dense mixture, known as LF-1A, JP-TS (thermally stable), or JP-7, with a boiling point of $ 3 0 0 ^{\circ} \mathrm{F} $ at sea level. Manufacturing this special fuel required petroleum byproducts that Shell normally used to make its "Flit" fly and bug spray. In order to produce several hundred thousand gallons of LF-1A for the U-2 project in the spring and summer of 1955, Shell had to limit the production of Flit, causing a nationwide shortage. Because of the new fuel's density, it required special tanks and modifications to the aircraft's fuel-control and ignition systems. $ ^{32} $
Even more important than the problem of boiling fuel was the problem of boiling blood, namely the pilot's. At altitudes above 65,000 feet, fluids in the human body will vaporize unless the body can be kept under pressure. Furthermore, the reduced atmospheric pressure placed considerable stress on the pilot's cardiovascular system and did not provide adequate oxygenation of the blood. Keeping the pilot alive at the extreme altitudes required for overflights therefore called for a totally different approach to environmental equipment; it required a system that could maintain pressure over much of the pilot's body. The technology that enabled U-2 pilots to operate for extended periods in reduced atmospheric pressure would later play a major role in the manned space program.
Advising the Agency on high-altitude survival were two highly experienced Air Force doctors, Col. Donald D. Flickinger and Col. W. Randolph Lovelace, II. Dr. Lovelace had begun his research on high-altitude flight before World War II and was a coinventor of the standard Air Force oxygen mask. In the early 1950s, he and Flickinger made daring parachute jumps from B-47 bombers to test pilot-survival gear under extreme conditions. Flickinger served as the medical adviser to Project AQUATONE for almost a decade. $ ^{33} $
Flickinger and Lovelace suggested that the Agency ask the David Clark Company of Worcester, Massachusetts, manufacturer of environmental suits for Air Force pilots, to submit designs for more Not linked to a story yet.
