The 1952 Washington, D.C., UFO incident, also called the "Washington flap" or the "Invasion of Washington", was a series of radar and visual sightings of unidentified objects over the U.S. capital between 12 and 29 July 1952, the peak of the largest UFO wave of the 1950s. The most publicised sightings came on the weekends of 19–20 and 26–27 July, when radar at two airports tracked unknown targets over restricted airspace and fighter jets were sent to intercept. The Air Force blamed temperature inversions, but the episode alarmed the CIA and led to the Robertson Panel.[1][2]
19–20 July
At 11:40 p.m. on 19 July, air traffic controller Edward Nugent at Washington National Airport saw seven objects on his radar about 15 miles south-southwest of the city where no known aircraft were flying. Senior controller Harry Barnes watched them and had technicians confirm that the radar was working normally. Controllers in the airport tower, Howard Cocklin and Joe Zacko, reported their own radar returns and a hovering bright light.[1]
At nearby Andrews Air Force Base, airmen reported an orange, fireball-like object with a tail and an orange-red light that changed direction suddenly, and Andrews radar tracked an object that disappeared from all three radar stations at the same moment. Capital Airlines pilot S.C. Pierman, waiting to take off in a DC-4, watched six white, tailless lights over about 14 minutes; Barnes said each sighting matched a radar return near the plane.[1]
At about 3 a.m., two F-94 Starfire interceptors arrived from New Castle Air Force Base in Delaware. The targets vanished from radar while the jets were present and reappeared after they left, leading Barnes to suspect the objects were listening to radio traffic. The last radar contact was at 5:30 a.m.[1]
Publicity
The sightings made front-page news across the country; one headline read "SAUCERS SWARM OVER CAPITAL". Project Blue Book head Capt. Edward Ruppelt was in Washington but did not hear of the sightings until 21 July, and returned to Dayton after being refused a staff car to investigate. An aide to President Harry Truman called Ruppelt about the reports, with Truman listening in.[1][3]
26–27 July
On the evening of 26 July, a National Airlines crew reported lights near their aircraft, and radar at National and Andrews soon tracked unknown objects again, with speeds calculated at up to 7,000 mph. Blue Book press officer Albert Chop refused reporters' requests to photograph the radar scopes. At about 11:30 p.m. two more F-94s arrived. The flight leader saw nothing, but his wingman, Lt. William Patterson, saw four white glows and gave chase; according to Chop, Patterson radioed: "I see them now and they're all around me. What should I do?" After midnight, Maj. Dewey Fournet of Air Force intelligence and Navy radar expert Lt. John Holcomb reached the radar room; Holcomb judged that the temperature inversion that night was too weak to explain the solid returns. As on the previous weekend, the sightings ended at sunrise.[1][3]
The Samford press conference
On 29 July, Maj. Gen. John Samford, director of Air Force intelligence, and Maj. Gen. Roger Ramey held a press conference at the Pentagon, the largest there since World War II. Samford said the visual sightings were probably stars, meteors or city lights, and the radar targets were probably caused by temperature inversions bending radar beams. He said the targets were not solid objects and posed no threat. A Civil Aeronautics Administration study later reported that inversions were present in almost every case.[1][4]
Debate
Ruppelt wrote that many radar operators and some Air Force officers disagreed with the explanation, and psychologist Michael Wertheimer found in 1966, for the Condon study, that radar witnesses still rejected it. Howard Cocklin told The Washington Post in 2002 that he still believed he had seen an object.[1][5] Skeptics including Harvard astronomer Donald Menzel and Philip Klass supported the inversion explanation, noting that radar of the period could not filter out weather effects, birds or balloons.[1]
Consequences
The CIA formed a study group, and on 24 September 1952 its Office of Scientific Intelligence warned that UFO reports could cause mass hysteria or clog warning systems in a crisis. In January 1953 the agency convened the Robertson Panel, chaired by physicist Howard P. Robertson, which recommended removing the "special status" given to UFOs and reducing public interest in them — recommendations that shaped Air Force policy for years.[1][6]
