JAL 1628 Flight Incident: The 1986 Alaska Encounter

On November 17, 1986, Japan Airlines Flight 1628 traveling from Reykjavik to Tokyo witnessed a close encounter with a massive unidentified flying object above Alaska. This incident, involving an experienced crew and documented by multiple ground witnesses, remains one of the most credible and studied UAP cases in commercial aviation history.

On November 17, 1986, Japan Airlines Flight 1628, a Boeing 747-200F cargo aircraft, was approaching Fairbanks International Airport in Alaska as daylight faded. The crew, composed of Captain Kenjyu Terauchi, an experienced pilot, and his two officers, was flying at an altitude of approximately 35,000 feet when it detected two unidentified flying objects on its radar screens.

Context

JAL 1628 was a regular cargo flight operating on the international commercial route connecting Reykjavik in Iceland to Tokyo. The Boeing 747 was a modern and reliable aircraft, equipped with the most advanced navigation and detection systems of that era. The crew consisted of experienced pilots: Captain Terauchi had logged more than 10,000 flight hours. The Cold War context made the Alaska region particularly monitored, with significant military presence and sophisticated radar systems covering the region.

The Facts

At approximately 17:11 (local time), Captain Terauchi reported abnormal radar activity, followed by visual observations. The crew described a massive object, estimated between 2,000 and 3,000 feet in length, possessing

Pentagon-linked investigation documents claim of strange creatures and a possible portal near Utah's Skinwalker Ranch from a 2010 BAASS investigation that interviewed over 25 witnesses.

Pentagon Reveals Bigelow's Secret Underground Vault for Exotic UAP Materials

Newly declassified Pentagon documents reveal that aerospace contractor Bigelow Aerospace developed architectural plans in 2009 for a heavily fortified 5,000-square-foot underground vault designed to store recovered hardware and biological specimens related to UAP investigations. The facility, never publicly disclosed until now, featured reinforced concrete walls three feet thick and was meant to be buried 15-20 feet underground at Bigelow's North Las Vegas operations, with plans to acquire exotic materials from private individuals and international sources including Brazil.
