The 1952 D.C. Flap

Jets scrambled over the White House. The objects left when the jets came, and returned when they refueled.

July 19-20 and 26-27, 1952: radar at Washington National and Andrews AFB tracked multiple unknowns over the capital, visually confirmed by airline pilots and tower personnel; jets scrambled, objects departed and returned. The Air Force's July 29 press conference — the largest since WWII — attributed it to temperature inversions, an explanation the radar operators publicly rejected. CIA concern about signal-to-noise in reporting channels led to the 1953 Robertson Panel, which recommended debunking as policy. The event links Blue Book (its busiest file), mass sightings, and the documented origin of official ridicule as a management tool.
