The Washington, D.C., sightings
Washington National Airport, Andrews AFB and surrounding airspace

Witness account
Radar operators and aircrew reported unusual targets around Washington on two successive July weekends. Interceptors were dispatched, and press attention made the episodes a national event. Reports came from different stations, observers and times; a continuous, fully correlated radar-and-visual track should not be presumed from the popular shorthand “UFOs over the Capitol.”
Public record
Contemporary operations accounts, witness interviews, military explanations and a later Civil Aeronautics Administration radar study document the incidents. General Samford’s major Pentagon press conference took place on 29 July.
