JAL pilot
sees lights
in the sky
Object doesn’t show
on military, FAA radar
By DON HUNTER
Daily News reporter
For the second time in two
months, a Japan Air Lines
pilot has reported seeing an
unknown object flying near
his airplane over barren inte-
rior Alaska.
Capt. Kenjyu Terauchi re-
ported the second sighting at
about 7:30 a.m. Sunday morn-
ing, as he, a co-pilot and a
flight engineer flew at about
37,000 feet, said Paul Steucke,
a spokesman for the Federal -
Aviation Administration. As
on the night of Terauchi’s
first report in November, he
was flying cargo in a Boeing
747 from London to a refuel-
ing stop in Anchorage.
There are more differences
than similarities between the
two reports, however.
Unlike last time, the lights
Terauchi saw Sunday morn-
ing did not show up on mili-
tary or FAA radar screens.
The pilot himself told FAA
investigators there was “no
similarity’? between the flash-
ing amber and white lights he
saw Sunday and the massive.
flying object. that Terauchi
reported trailed his aircraft
for hundreds of miles on Nov.
17, Steucke said.
As on the first sighting,
Terauchi was accompanied by
a co-pilot and a flight engi-
neer. They were not the same
crew members, Steucke said.
Steucke said the cargo
plane’s co-pilot was flying the
plane at the time of the sight-
ing Sunday morning. The co-
pilot reported seeing the
lights, but did not watch
them as long as Terauchi. The
aircraft's flight engineer, who
sits farther back in the cock-
pit, ‘indicated he was uncer-
_ tain whether he saw any
lights at all,’’ Steucke said.
‘We asked him point-blank
if this was like the Nov. 17
Sighting and he said, ‘no, no,

there’s no similarity between
the two,’’’ Steucke said.
Terauchi reported seeing
the lights twice Sunday morn-
ing, once for a period of about
20 minutes and once for about
10 minutes. In both cases, he
said the lights approached
from the front of the 747,
went underneath the aircraft
and reappeared behind it,
Steucke said.
Terauchi radioed word of
the sighting to an air traffic
controller in Anchorage.
“His statement to the con-
troller was ‘irregular lights,
looks like a spaceship,’ ”’
Steucke said.
Controllers and their super-
visors immediately checked
radar screens ‘‘to see if there
were any objects around the
JAL aircraft,’ Steucke said.
“There were none, and that
was confirmed” by military
radar, he said.
Steucke said FAA officials
and experienced pilots specu-
late that Sunday’s sighting
could have been caused by a
weather phenomenon called
‘bounce light effect.”
Both times Terauchi report-
ed seeing the lights Sunday,
the airplane was flying over
villages, Steucke said.
“The ground temperature
in the area was about minus-
23 and there was. a tempera-
ture inversion at 23,500 feet,”’
he said. ‘‘Temperature inver-
sions in cold climates, with
ice crystals, have been known

Lights in sky
to create a bounce light ef-
fect.’’
Light from the villages
could have reflected off ice
crystals in the inversion and
appeared to be hovering in
mid-air, Steucke said. As the
plane approached and passed
over the villages, the reflect-
ed light would have appeared
to go under the aircraft and
reappeared behind it, as Ter-
auchi described the lights he
saw Sunday, Steucke said.
Steucke said the bounce-
light theory is only specula-
tion, not an agency finding.
“Those of us involved in this
talked about it,’’ he said.
‘People who are experienced
at flying mentioned that it is
not an infrequent occur-
rence.”’
On Nov. 17, Terauchi re-
ported that two brightly lit
objects and a much larger
third object — roughly twice
the size of an aircraft carrier
— trailed the JAL plane for
more than 300 miles as it
crossed into Alaska from Ice-
land.
Terauchi said the objects
changed altitude with him
and paced the jet for nearly
an hour. In Anchorage, air
traffic controllers monitoring
the JAL plane’s progress saw
what appeared to be the radar
tracks of another flying ob-
ject in the air space near
_ Terauchi’s plane.
Both incidents are under
investigation, Steucke said.
Terauchi could not be
reached for comment Sunday.
