In this episode of Mysteries of UFOs, we revisit the Washington D.C. UFO Flap of 1952, one of the most dramatic and well-documented mass UFO events in history. Over two consecutive July weekends, multiple radar stations, commercial pilots, military personnel, and civilians witnessed fast-moving glowing objects maneuvering over the U.S. capital.
Radar tracked the objects accelerating, stopping midair, and moving at thousands of miles per hour—far beyond the capabilities of any aircraft of the time. When the military scrambled F-94 jets to intercept, the objects vanished, only to reappear moments later elsewhere on radar. Witnesses described orange or white lights hovering over the Capitol and the White House.
Newspapers exploded with headlines, causing nationwide panic. In response, the Air Force held an emergency press conference, attributing the sightings to temperature inversion, though radar experts and meteorologists strongly disputed this explanation. Project Blue Book investigated but never provided a definitive answer.
The Washington Flap remains one of the strongest cases of coordinated radar-visual UFO activity over restricted airspace, leaving behind a legacy of unanswered questions and enduring intrigue.
