UFOs over Washington DC

The 1952 Washington, D.C., UFO incident involved a series of unidentified flying objects (UFOs) being detected on radar and witnessed by both civilian and military personnel. Over multiple nights in July, radar operators at Washington National Airport and nearby Andrews Air Force Base reported unusual blips and movements in the airspace. Fighter jets were scrambled to intercept, but the objects appeared to outmaneuver them and vanished. The sightings sparked public and government interest, leading to hearings in Congress and speculation about extraterrestrial origins. Ultimately, the U.S. Air Force attributed the sightings to temperature inversions causing radar anomalies, but the incident remains a subject of debate among UFO enthusiasts and researchers.
