Washington National Airport radar-visual incident

Record summary

In July 1952, radar operators and aircrew around Washington National Airport and nearby bases reported unusual targets, with visual observations accompanying some radar returns. The incidents prompted military scrambling, press coverage, and a high-level briefing. Air Force explanations emphasized temperature inversions and radar propagation anomalies, while some witnesses disputed conventional accounts. This is a central radar-visual case for studying detection limits, command response, and public communication. The individual tracks and later interpretations require reconstruction from operational records.
