Dozens of residents around Stephenville, Texas, report large, fast-moving, brightly lit objects in the night sky. A subsequent FOIA release of FAA radar data confirms anomalous tracks consistent with witness reports.
Aircrews from the USS Nimitz Carrier Strike Group report repeated radar contacts and a daylight visual encounter with a small, white, smooth, Tic Tac–shaped object during a training exercise in the Pacific. One of three Pentagon videos later released by the Department of Defense (FLIR1) documents a portion of the event.
Hundreds of witnesses across Belgium, including dozens of national and federal police officers, report large, silent, triangular craft moving at low altitude over the country. The Belgian Air Force scrambles F-16s on 30–31 March 1990 and obtains a brief radar lock that is later attributed to anomalous propagation.
Capt. Kenju Terauchi reports two small craft and a much larger, walnut-shaped 'mothership' alongside a Japan Airlines 747 cargo flight transiting Alaskan airspace. The objects are corroborated by FAA ground radar at Anchorage Center.
Two Imperial Iranian Air Force F-4 Phantoms intercept an unidentified object over Tehran. Both pilots report electronic-system failures, and one reports temporary loss of weapons control. A four-page Defense Intelligence Agency report on the case is later released under FOIA.
Across two consecutive weekends, multiple radar installations and visual observers track unidentified objects above the restricted airspace surrounding the U.S. Capitol and White House. The Air Force convenes its largest press conference since World War II to address the events.
