The A-12 is an aircraft built for strategic, high-altitude reconnaissance. It’s a spy plane, of course! The airplane is meant to outrun enemy air defenses to bring back intelligence for the CIA. The aircraft flew until 1968, and now, the public can see photos of the intelligence aircraft that have been shared by Thornton “TD” D. Barnes, who worked on the spy plane at Area 51.
