Captain Terauchi reported seeing a group of unusual lights appear in front of his
aircraft at what ·appeared to be approximately 2,000 feet below his altitude of
FL370 , and then disappeared under the nose of the airplane at approximately 240
nautical miles north of Nenana, Alaska. This phenomenon occurred again at approxi
mately 151 nautical miles north of Nenana but this time the lights appeared at
his 10: 00 position and slowly moved to the 9:00 and 8:00 positions before dis-
appearing. During an interview with the flight crew conducted at Anchorage, it
was noted that the aircraft flight path was north of and directly over the villag1
of Arctic Village, Alaska at the time of the first sighting and 45 nautical miles
northwest and west of the village of Fort Yukon duri ng the second sighting.
Captain Terauchi now believes that the unusual lights he saw were those village
lights that had been obscured or changed by ice crystals present in the atmospher1 . !

The following is a report concerning the incident to Japan Airlines Flight
628, (JL628), on January 11, 1987 at approximately 1629 UTC.
My name is Ricky Thompson (RT). I am employed as an Air Traffic Control
Specialist by the Federal Aviation Administration at the Anchorage Air Route
Traffic Control Center (ARTCC), Anchorage, Alaska.
During the period of 1430 UTC, January 11, 1987 to 2230 UTC, January 11,
1987, I was on duty in the Anchorage ARTCC. I was working the R/Dl5 position
from 1422 UTC, January 11, 1987, to 1632 UTC, and the Rl5 position from 1632
UTC, January 11, 1987, to 1645 UTC, January 11, 1987.
At approximately 1629Z, JL628 reported an object at his 12 o'clock position 5
miles, and 2000' below him. He stated that it was not an aircraft and then
made a statement in Japanese. The pilot then requested 45° turns and I
approved his r equest. The Regional Operations Control Center, (ROCC), called
me and said the only aircraft in that area was JL628.
I adjusted the radar scale to 400NM, and soon picked up a primary target. A
few minutes later I identified the target as JL628, 220NM north of
Fairbanks. I centered the radar scope on JL628 and reduced the scale, but
saw no othe r targets. At 1632 UTC, Gail Ferguson relieved me on the Dl5
position and at 1646 UTC she assumed the R/Dl5 combined position. I had no
further contact with JL628.

I assumed the duties of the AMIC position at 1635Z, on January 11, 1987, at
the Anchorage ARTCC. My relief briefing included a pending situation
involving JL628 reporting a UFO sighting in the vicinity of FYU. I advised
the Facility Manager, ZAN-600, Regional Operations Center (ROC), and Regional
Operations Control Center (ROCC). I contacted the ROCC at approximately
1642Z; the Senior Director indicated that no targets other than JL628 were
observed. I monitored the radar display myself and did not observe any
unknown targets, only weather clutter. The CWSU advised me that there was a
temperature inversion in the area of JL628's route of flight. I was advised
the pilot stated that he lost contact with the UFO at approximately 1658Z.
The remainder of the flight was handled in a normal manner. I turned all
information over to ZAN-600 for further investigation.

(JL628), on January 11, 1987, at approximately 1629 UTC.
:My name is Gail Ferguson (GF). I am employed as an Air Traffic Control
Specialist ty the Federal Aviation Administration at the Anchorag e Air Route
Traffic Control Center (ARTCC), Anchorage, Alaska.
During the period of 1 630 VIC, January 11, 1987, to 0030 UTC, January 12,
1987, I •:as on duty in the Anchorage ARTCC. I was working the Dl5 position
from 1632 UTC, January 11, 1987, to 1645 UTC, January 11, 198 7 and the R/Dl5
position from 1646 UTC, January 11, 1987 to 1802, UTC, January 11, 1987.
I
arrived for my scheduled shift and ~as told to plug into the Dl5 position to
help Ricky Thompson (RT) because JL628 was reporting an unidentified object.
While RT was working the Rl5 position, I heard JL628 request direct ENN and
advise that traffic had disappeared. I then called Edmonton to take a
transfer on JL6 78. I heard RT ask JL628 if the traffic was in sigtt, and was
told "negative".
After I relieved RT on the Rl5 position, JL628 asked me if there was traffic
in his area and said he was seeing something in the 10 o'clock position at 5-7
miles. I replied "negative". He said he could see navigational lights same
direction, about 2000 feet lower, and a little slower. I responded "negative,
nothing in the area".
I gave traffic information to JL628 on N441VP, (Conquest), 12 o'clock, 125
miles, northbound at FL310. JL628 said he now saw traffic at 9 o'clock, 2000
feet below, 2-3 miles i1ith some kind of navigation lights, flying like a
formation flight. I asked him to verify 9 o'clock and received no reply. I
asked him to say again position and received no reply . I asked him again for
a position and JL628 gave n:e his position, 6638N 1 4702W. I responded that I
didn't need his position and asked him to say position of object. I then told
him that I understood he no longer saw the object -reply was unreadable.
JL628 then said he was signaling with his landing lights and it looked like
the object was responding (this transmission was very difficult to
understand). I asked ''understand object is responding to your signal" and was
told "I' 11 tell you after landing". l-]e asked for traffic information on
something 2 o'clock and 5 miles -I gave him the position of the Conquest
aircraft at 2 o'clock and 1 5 miles northbound at FL310.
The ROCC called and asked about the Conquest. I told him I had given JL628
that traffic. Later JL628 said the object had disappeared.

watched the Facility Coordination Officer's scope and observed weather
clutter just ahead of JL628. In my experience at Anchorage ARTCC working R/D
