The Lockheed A-12 Oxcart was brought to Area 51-Nevada for Test Flight and to set ready for Operation "Black Shield." The A-12 Blackbird was chased by the McDonnell Douglas F-101 Voodoo. The F-101 was integral to the Oxcart Program along with the incredible USAF support for the entire Oxcart Program. The CIA, which ran the Oxcart Program could not have made it without the support of the USAF.
