I dug into this issue a bit and found the "complete report." Although a fascinating read I have found what appear to be a few inconsistancies and I quote:
1: "A bright moon helped with the visibility for the night flight over Greenland, but as the plane continued over northern Canada the moon set behind them.
When the plane reached an air route reporting point in far northwestern Canada called "Shingle Point" the sky ahead was dark
except for an afterglow of sun in the west."
Although I realize that while traveling on a subsonic airliner, heavenly bodies such as the Moon and Sun are sort of "frozen in time" when flying from east to west, I don't believe the Moon would set behind them after first having "aided with visibility", implying it was near its zenith for most of the flight? The Moon sets in the West, not the East, you would have to fly well into the supersonic range to have it set behind you. I have flown several times on such routes (subsonically) and you usually lose a few hours between local take-off time and local landing time. Meaning that Sun and Moon would still set in the West, not East.
2: "The United Airlines aircraft was coming close to us. We knew that they were watching us. When the United plane came by our side the spaceship disappeared suddenly and [b]there was nothing left but the light of the moon."['b]
The moon had set, hadn't it?
Furthermore the report refers to the fact that the crew had refused an offer from ATC to have airforce jets scramble from only 40 miles away to investigate?
ATC asked a United flight to check while flying an opposite course relative to the JAL flight.
3: "When the planes were about 12 miles apart and still approaching one another, the UA
plane reported seeing the JAL plane and nothing else. By this time the "mothership" had apparently disappeared:
5:50:35 UA69 - UA69 heavy. We've got the Japan Airliner in sight. I don't see anybody around him. He's (referring to the "spaceship") at his seven o'clock position, huh?"
Refusing an offer from ATC and when opposing traffic only spots the JAL flight leaves a few questions to be answered. One of them is: have the crew during the flight been in the cargo compartment? After all, the cargo included a shipment of French wine . . .
