Record summary
During two heavily publicized nights in July 1952, radar operators at Washington National Airport and Andrews Air Force Base reported unidentified returns, while pilots and controllers described lights or objects near the capital. Intercepts were attempted, and the press connected the events with the Potomac and nearby waterways. Air Force reviews considered temperature inversions and radar propagation among possible explanations, while some witnesses rejected purely meteorological accounts. The case matters for studying maritime-adjacent airspace, radar interpretation, and Cold War command responses.
