Have UFOs Been Reported in the United States?

Yes. Reports and sightings of unidentified objects have been documented in the United States. But a report alone does not prove that an object was a spacecraft or that its occupants came from beyond Earth. UFO means an unidentified object; the term says nothing about where it came from.

An FBI file documents an investigation into reports in Washington state from July 1952 to August 1960, including correspondence with the US Air Force [1]. Another FBI file covers reports in and around New Jersey from August 1952 to January 1967 [3]. These documents record reports and investigations; they do not confirm that the objects were extraterrestrial craft.

A CBS LA article also describes reports of sightings over Catalina Island in the 1940s and 1950s [4]. Investigation files may include testimony or accounts of events that were never clearly explained. A joint US-Canada file describes an incident near Newfoundland, not in the United States, in which an aircrew saw an object while radar returns were also recorded. The committee could not explain the returns [2]. The American reports establish that unidentified sightings were documented. The sources do not establish what the objects were or prove that aliens visited the United States [1][3][4].
