Sighting by Date: 1950 – 1999 Sightings
The period between 1950 and 1999 defines the modern UFO phenomenon, characterized by intense military scrutiny and widespread public fascination. From the massive 1952 Washington, D.C. radar flap that alarmed the Truman administration to the official investigations of Project Blue Book, this era moved UAPs from fringe rumors into a matter of national security. These decades also introduced the first widely publicized reports of close encounters and abductions, forever changing our cultural understanding of potential extraterrestrial contact.
1950 – 1959 Sightings
The 1950s were the ‘heyday’ of flying saucers, dominated by the Washington National Airport sightings and the US Air Force’s formal efforts to categorize and explain thousands of reports through projects like SIGN, GRUDGE, and BLUE BOOK.
