What happened to JAL Flight 1628?

On November 17, 1986, Captain Kenju Terauchi reported that his Japan Airlines 747 was paced by luminous objects, followed by an enormous walnut- or Saturn-shaped craft he estimated to be larger than an aircraft carrier. The encounter lasted roughly 50 minutes across the Alaskan night sky.
