Project Blue Book Case #1732. On July 29, 1952, an unidentified object was observed over Langley Air Force Base in Hampton, Virginia — the headquarters of Tactical Air Command (TAC), which controlled all USAF fighter, attack, and reconnaissance operations. An unknown over TAC headquarters was an unknown over the command center of America's air combat capability.
Langley sat at the heart of the Hampton Roads military complex — the densest concentration of military facilities on the East Coast. July 29 was during the peak wave, two days after the second Washington radar events. The case was classified "Unknown."
