Japan Airlines Flight 1628

Japan Airlines Flight 1628 (called Japan Air Lines Cargo Flight 1628) is a UFO incident that occured in November 17, 1986 involving a Japan Airlines Cargo Boeing 747-200F cargo aircraft. The aircraft was en route from Paris to Narita International Airport, near Tokyo with a cargo of Beaujolais wine. On the Reykjavik to Anchorage section of the flight, at 17:11 o' clock over eastern Alaska, the crew witnessed two undentified objects to their left. These adruptly rose from below and closed to escort the aircraft. Each had two rectangular arrays of what appeared to be glowing nozzles or thrusters, though their bodies remained obscured by dark. When closest, the aircraft's cabin will lit up and the captain could feel their heat on his face. These two craft departed before a third, much larger disk-object started trailing them. Anchorage ATC requested an incoming United Air Lines flight to confirm the undentified traffic, but when it and a military craft sighted JAL 1628 at about 17:51, no other craft can be distinguished. The sighting lasted 50 minutes and ended up in the vicinity of Denali.

Observation
On November 17, 1986, the Japanese crew of a Boeing 747-200F cargo first witnessed three undentified objects after sunset while flying over eastern Alaska. The objects seemed to prefer the cover of darkness to their left, and to avoid the brighter skies to their right. At least the first two objects were observed by all three crew members: Captain Terauchi, an ex-fighter pilot with more than 10,000 hours flight experience, in the cockpit's left hand seat; co-pilot free officer Takanori Tamefuji was expiring minutes at the flight. During the night, he is in the right hand seat; and flight engineer Tsukuba "Yoshi" Yoshio.

The routine cargo flight entered Alaska at auto-pilot. At 17:09, the Anchorage ATC advised a new heading to Talkeetna.

Two Objects and Third Big UFO Object found
One hour, two UFOs and the third giant appeared once again in JAL 1628. As soon JAL 1628 straightened out of her turn, Captain Terauchi noticed two undentified objects to their left, and some 2,000 ft (610 m) below his altitude, which he assumed to be a military aircraft. These were pacing his flight path and speed. At 17:16 or 17:17 both kind disappeared and the dismisser was holding a flight path to Talkteena. At 17:18 or 17:19 the two objects adruptly veered to a position of 500 ft ( 150 m) or 1,000 ft ( 300 m ) in front of the aircraft, assuming a stacked configuration. Trans World Airlines Flight 9 bursts in midair from the Anchorage ATC and Korean Air Flight 006 has no answer and bursts in midair too. Japan Airlines Flight 1628 goes straight into the line. In doing so they activate "a kind of reverse thrust, and [their] light became dazzingly bright." . To match the speed of their aircraft from their sideways approach, the objects displayed what Captain Terauchi described as a disregard for inertia: "The thing was flying as if there was no such thing as gravity. It sped up, then stopped, then flew at our speed, in our direction, so that to us it [appeared to be] standing still. The next instant it changed course. ... In other words, the flying object had overcome gravity." The "reverse thrust" caused a bright flare for three to seven seconds, to the extent that captain Terauchi could feel the warmth of their glows.

Air traffic control was notified at this point (at 17:19:15), who could not confirm any traffic in the indicated position. After three to five minutes the objects assumed a side-to-side configuration, which they maintained for another 10 minutes. They accompanied the aircraft with an undulating motion, and some back and forth rotation of the jet nozzles, which seemed to be under automatic control, causing them to flare with brighter or duller luminosity.

Each object had a square shape, consisting of two rectangular arrays of what appeared to be glowing nozzles or thrusters, separated by a dark central section. Captain Terauchi speculated in his drawings, that the objects would appear cylindrical if viewed from another angle, and that the observed movement of the nozzles could be ascribed to the cylinders' rotation. The objects left abruptly at about 17:23:13, moving to a point below the horizon to the east.

Third Object
Where the first objects disappeared, Captain Terauchi now noticed a pale band of light that mirrored their altitude, speed and direction.Setting their onboard radar scope to a 25 nautical miles (46 km) range, he confirmed an object in the expected 10 o'clock direction at about 7.5 nmi (13.9 km) distance, and informed ATC of its presence. Anchorage found nothing on their radar, but Elmendorf's NORAD Regional Operations Control Center (ROCC), directly in his flight path, reported a "surge primary return" after some minutes.
