Washington, D.C.

The capital of the United States and the epicenter of American government and military leadership. It is most famous in UAP history for the July 1952 UFO wave, where multiple unidentified objects were tracked on radar and visually observed flying over the White House and the Capitol, prompting jet scrambles and a major Air Force press conference. The postal code 'Washington 25, D.C.' was historically used for military correspondence, including Project Blue Book files.

Site of the monumental 1952 radar-visual UFO wave over restricted airspace, which forced the US government to publicly address the phenomenon.
