American Alchemy / Jesse Michels ↗YouTube-hosted preview and player; not relicensedOn 17 November 1986 Captain Kenju Terauchi of JAL cargo flight 1628 reported two lighted objects and then a very large object pacing his 747 over Alaska for about 50 minutes; Anchorage controllers and military radar briefly saw returns. The FAA released its file in 1987 without explanation. Corpus guests show Terauchi's sketch and cite the radar.

What was reported. Flying a Boeing 747 freighter from Paris to Tokyo via Anchorage, Captain Terauchi reported two small lighted craft ahead of the aircraft near Fort Yukon, then a huge object silhouetted against the night sky that he compared to two aircraft carriers. He requested turns and a descent; the objects stayed with him for about fifty minutes. (FACT about the report.)
What followed. Anchorage ARTCC and Elmendorf AFB radar briefly reported a primary return near the aircraft. The FAA investigated, released its file in 1987 and said the radar return was probably a split image. Terauchi was grounded for a period. (FACT.)
What the corpus adds. In the NASA-whistleblower episode the case is presented with Terauchi's own sketch; in the 2026 skeptic debate the host cites a Japan Airlines pilot flying for 45 minutes with radar that was confiscated as an example of witnesses plus radar. (FACT about testimony.)
Explanations offered. Skeptics attribute the lights to Jupiter and Mars, low on the horizon in that direction, and the large shape to clouds; supporters cite Terauchi's experience and the radar return. (INFERENCE.)
