Washington, D.C.; July 19, 1952
The legend: Early in the history of ufology (the study of unidentified flying objects) in the United States, extra-terrestrial visitors may made themselves known to the leaders of the free world by allegedly buzzing over the White House, the Capitol building, and the Pentagon. Washington National Airport and Andrews Air Force Base picked up a number of UFOs on their radar screens on July 19, 1952, beginning a wave of sightings that are still unexplained to this day.
Rosetta/Natal, South Africa; July 17, 1956
