The Reports:
The summary of the communication between JAL Captain Terauchi and ground controllers was published by the Federal Aviation Administration:

6:19 PM local time: The pilot of JL1628 requested traffic information from the ZAN (FAA Air Route Traffic Control Center, Anchorage) Sector 15 controller.

6:26 PM: ZAN contacted the Military Regional Operations Control Center (ROCC), and asked if they were receiving any radar returns near the position of JL1628. The ROCC advised that they were receiving a primary radar return in JL1628's 10 o'clock (left-front) position at 8 miles [13 km.].

6:27 PM: The ROCC contacted ZAN to advise they were no longer receiving any radar returns in the vicinity of JL1628.

6:31 PM: JL1628 advised that the 'plane' was 'quite big,' at which time the ZAN controller approved any course deviations needed to avoid the traffic.

6:32 PM: JL1628 requested and received a descent from FL350 to FL310 (flight level 350 and 310, meaning altitude of 35,000 and 31,000 feet, or 10,500 m. and 9,500 m.). When asked if the traffic was descending also, the pilot stated it was descending 'in formation.'

6:35 PM: JL1628 requested and received a heading change to two one zero (210 degrees, or southwest). The aircraft was now in the vicinity of Fairbanks and ZAN contacted Fairbanks Approach Control asking if they had any radar returns near JL1628's position. The Fairbanks Controller advised they did not.

6:36 PM: JL1628 was issued a 360 degree turn and asked to inform ZAN if the traffic stayed with them.

6:38 PM: The ROCC called ZAN advising they had confirmed a 'flight of two' in JL1628's position. They advised they had some 'other equipment watching this,' and one was a primary target only.

6:39 PM: JL1628 told ZAN they no longer had the traffic in sight.

6:42 PM: The ROCC advised it looked as though the traffic had dropped back and to the right of JL1628, however, they were no longer tracking it.

6:44 PM: JL1628 advised the traffic was now at 9 o'clock (left).

6:45 PM: ZAN issued a 10 degree turn to a northbound United Airlines flight, after pilot concurrence, in an attempt to confirm the traffic.

6:48 PM: JL1628 told ZAN the traffic was now at 7 o'clock (left rear), 8 miles [13 km.].

6:50 PM: The northbound United flight advised they had the Japan Airlines flight in sight, against a light background, and could not see any other traffic.

6:53 PM: JL1628 advised that they no longer had contact with the traffic."


The third phase occurred as the "ships" receded and could only be seen as "two dim, pale, white lights," but an echo was picked up by the aircraft on-board radar. While Maccabee concedes that the echo could have been caused by "a temporary (self-repairing) failure" (as suggested by the FAA), he added that "it seems much more likely that there was some object out there."

The last phase is perhaps the most controversial one, as Captain Terauchi was the only witness of the so-called giant spaceship "two times bigger than an aircraft carrier."

Maccabee conceded:
"It seems at least plausible that he may have misinterpreted oddly lighted clouds which the crew had reported to be below the aircraft. Although the several ground radar returns behind the jet were intriguing, the failure of the radar to show a continuous track of some unknown primary target makes the radar confirmation ambiguous at best. Therefore it seems that, at the very least, the last portion of the sighting is not so convincing as the earlier portions. "Even if one arbitrarily ignores that latter part of the 'Fantastic Flight of JAL1628' one is still left with an intriguing sighting of the two 'ships' which paced the aircraft. It seems, then, that the JAL1628 was accompanied during part of its flight by at least two TRUFOS (True UFOs)."
