Anchor incidents include the December 1980 Rendlesham Forest case (US Air Force personnel report close-encounter activity over a two-night window immediately adjacent to RAF Bentwaters' nuclear-weapons storage), the Cash–Landrum case (December 1980, Texas), the Trans-en-Provence landing-trace case (January 1981, GEIPAN's most-cited Class D file), the Brazilian Noite Oficial dos OVNIs (May 1986), JAL Flight 1628 over Alaska (November 1986), and the November 1989 opening of the Belgian wave.
The 1980s also produces the longest single-incident-investigation FAA file in the modern record: the thirty-volume Federal Aviation Administration case file on JAL 1628, released under FOIA in early 1987.
Why this matters. The 1980s record is broader and more documentary than the 1970s, with multiple cases producing primary-source case files at the national-archive level (Brazil's Arquivo Nacional, France's GEIPAN, the FAA, the UK MoD). It is the decade the international record matures into something a researcher can systematically consult.
