In February 1959, nine experienced Soviet hikers died under strange circumstances on a slope of the northern Ural mountains — their tent slashed open from inside, several bodies bearing severe internal injuries without external wounds, and faint radiation on some clothing. The unexplained deaths and Soviet secrecy spawned decades of theories ranging from secret weapons tests to yetis and UFOs, until modern investigations and a 2021 peer-reviewed study pointed to a rare delayed slab avalanche.

On the evening of 13 March 1997, two distinct aerial events over Arizona generated thousands of eyewitness reports and became one of the most widely documented mass-UFO-sighting events in American history. The first event — a V-formation of lights moving south from Henderson, Nevada through Phoenix to Tucson between roughly 8:15 and 8:30 p.m. — has been explained as five A-10 Thunderbolts flying in formation. The second event — stationary lights appearing over the Estrella Mountains south of Phoenix around 9:30 p.m. — was later identified by the US Air Force as LUU-2B/B illumination flares dropped by the Maryland Air National Guard's 175th Fighter Squadron during Operation Snowbird at Barry Goldwater Range. Governor Fife Symington III mocked the reports at a press conference but admitted in 2007 that he personally saw the formation.

Between November 1989 and April 1990, thousands of witnesses across Belgium — primarily in the Eupen and Wallonia regions — reported large, silent, triangular craft with bright lights at their corners. The Belgian Air Force took the reports seriously enough to scramble F-16 fighters on the night of 30–31 March 1990, and Col Wilfried De Brouwer publicly briefed the sightings in a rare military acknowledgement. The wave produced the famous Petit-Rechain photograph, long considered the best evidence of a structured craft — until 2011, when photographer Patrick Maréchal admitted it was a polystyrene model he had painted and photographed. The Society for the Study of Space Phenomena (SOBEPS) conducted two investigations but reached no definitive conclusion about the craft's origin.

In November 2004, F/A-18 Super Hornet pilots from USS Nimitz Carrier Strike Group encountered an unidentified aerial object off the coast of Catalina Island, California. Commanders David Fravor and Alex Dietrich witnessed a white, Tic-Tac-shaped craft performing maneuvers inconsistent with known aviation technology. FLIR footage was captured and later released publicly in 2017. The Pentagon confirmed the existence of its Advanced Aerospace Threat Identification Program (AATIP) following a New York Times investigation in December 2017. The encounters are real and documented; whether the objects are of extraterrestrial origin remains unestablished.
