Washington, D.C. radar-visual wave

Record summary

What happened On two July weekends, controllers at Washington National Airport and Andrews Air Force Base reported unidentified radar returns, while pilots and people on the ground described moving lights. Interceptors were launched, but pilots generally saw only lights at a distance and did not obtain decisive radar contact. The events produced intense national coverage and the largest Air Force press conference since World War II. Air Force specialists argued that strong temperature inversions could create anomalous radar propagation and make stars or city lights appear distorted; some controllers rejected that as a complete explanation. The incident is best understood as a cluster of radar and visual reports under unusual atmospheric conditions, not one continuously tracked craft. Evidence Multiple radar operators, pilots and ground witnesses; air-defense responses; weather data; contemporary military and press documentation. Original continuous radar recordings are not available. Explanations considered Temperature-inversion radar effects, stars, meteors and ordinary aircraft account for many elements. Critics note that trained operators described returns they believed behaved unlike weather ghosts. What remains uncertain Radar observations came from different scopes and times, and visual lights were rarely linked instrumentally to a specific return. Media attention probably increased reporting during the second weekend.
