The Washington, D.C. Flap

Catalog FG-019When July 19–27, 1952Where Washington, D.C.

Radar blips over the Capitol, jets scrambled and the biggest Pentagon press briefing since WWII.

On two weekends in July 1952, air traffic radar at National Airport and Andrews Air Force Base tracked unknown targets over the capital. Some pilots saw lights where the radar showed returns. Jets were scrambled but found little. The headlines grew so big that the Air Force held a large press conference on July 29.
