Documents / FOIA release
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.

On 29 April 1955, Richard Bissell signed an agreement with the Air Force and the Navy (which at that time was also interested in the U-2) in which the services agreed that the CIA "assumed primary responsibility for all security" for the overhead reconnaissance project (AQUATONE). From this time on, the CIA has been responsible for the security of overhead programs. This responsibility has placed a heavy burden on the Office of Security for establishing procedures to keep large numbers of contracts untraceable to the Central Intelligence Agency. The Office of Security has also had to determine which contractor employees require security clearances and has had to devise physical security measures for the various manufacturing facilities. Keeping the U-2 and subsequent overhead systems secret has been a time-consuming and costly undertaking. $ ^{25} $
The most important aspect of the security program for the U-2 project was the creation of an entire new compartmented system for the product of U-2 missions. Access to the photographs taken by the U-2 would be strictly controlled, which often limited the ability of CIA analysts to use the products of U-2 missions.
The terminology used to describe U-2 aircraft and pilots also played a part in maintaining the security of the overhead reconnaissance program. To reduce the chances of a security breach, the Agency always referred to its high-altitude aircraft as "articles," with each aircraft having its own "article number." Similarly, the pilots were always called "drivers." In cable traffic the aircraft were known as KWEXTRA-00 (the two-digit number identified the precise aircraft; these numbers were not related to the three-digit article numbers assigned by the factory). The pilots were referred to as KWGLITTER-00 (the two-digit number identified the precise pilot). Thus, even if a message or document about overflight activities fell into unfriendly hands, the contents would simply refer to codewords or at worst to "articles" and "drivers," giving no indication of the nature of the program.26
Even the aircraft's onboard equipment required the involvement of CIA security planners. Thus, when Kelly Johnson ordered altimeters from the Kollman Instrument Company, he specified that the Not linked to a story yet.
