Documents / FOIA release
This is a CIA History Staff monograph by Gregory W. Pedlow and Donald E. Welzenbach, written in 1992 and approved for release in 2011. It covers the CIA's manned overhead reconnaissance program from 1954 to 1974 and its two aircraft, the U-2 and the A-12 OXCART. It follows their development, the overflights of the Soviet Union, the downing of Francis Gary Powers in 1960, and later operations. One section is titled "U-2s, UFOs, and Operation BLUE BOOK."

'OXCART Story.- 005653421 UNCLASSIFIED SecrefT Chapter 6 284 EO 129581.61d1[11>1010<25Yrs (Si storage capacity, and runway length were insufficient for the OXCART program, the site's remote location would greatly ease the task of maintaining the program's security, and a moderate construc- tion program could provide adequate facilities. Construction began in September 1960; a C-47 shuttle service ferried work crews from Burbank to Las Vegas and from Las Vegas to the site. The new 8,500-foot runway was completed by 15 November 1960. Kelly Johnson had been reluctant to have a standard Air Force runway with expansion joints every 25 feet because he feared the joints would set up undesirable vibrations in the speedy aircraft. At his suggestion a 150-foot wide runway was therefore constructed of six 25-foot-wide longitudinal sections, each 150 feet long but stag- gered. This layout put most of the expansion joints parallel to the di- rection of aircraft roll and reduced the frequency of the joints. Additional improvements included the resurfacing of 18 miles of hi g hway leading to the base so that heavy fuel trucks could bring in the necessary fuel. The need for additional buildings on the base was met by the Navy. Three surplus Navy hangars were dismantled, moved, and reassembled on the north side of the base, and more than 100 surplus Navy housing buildings were also transported to All essential facilities were ready in time for the forecast delivery date of the first A-12 on 1 August 1961.' Unfortunately, this delivery date began to slip further and further into the future. Delays in obtaining the titanium, and later the 158 en- gines, caused the postponement of the final assembly of the first plane. Eventually, Kelly Johnson and Agency project officials decided to be- gin testing without waiting for the 158 engines by using Pratt & Whitney J75/ I9W engines, designed for the Convair F-106, to test the A-12 at altitudes up to 50,000 feet and at speeds up to Mach 1.6. Such a change, however, meant that the en g ine compartment of the first air- craft had to be reconfigured to accommodate the J75 en g ine. Lockheed hoped that this substitution would permit the delivery of the first A-12 by 22 December 1961 and its initial test flight by 27 February 1962. Lockheed ran into so many technological problems with the OXCART effort that by October 1961 its costs had swollen to $136 million and were still climbing. Something obviously had to be done OSA Histbry. chap. 20. pp. 39-40, 43, 51 (TS Codcword) pp. 7-9 (S). UNCLASSIFIED
