CIA historian Gerald Haines (1997) wrote that over half of late-1950s–60s UFO reports were manned reconnaissance flights (U-2, OXCART), and that the Air Force 'made misleading and deceptive statements to the public in order to allay public fears and to protect an extraordinarily sensitive national security project.' The CIA's full U-2/OXCART history was re-released in PURSUE R03.
