Package compiled for FAA managers
FAA via National Archives / The Black Vault · 122 pages · text from the file's own layer
This package was compiled by the FAA Alaskan Region Public Affairs Office in Anchorage and sent to FAA managers with a memo from Paul Steucke dated March 5, 1987. It gathers material on the November 17, 1986 sighting by the crew of Japan Air Lines flight 1628: a news release, pilot and controller transcripts, crew interviews and radar analysis. The FAA concluded that it could not confirm the event. It attributed the second radar target to a split, uncorrelated return from the JAL Boeing 747 and planned no further investigation.

ANALYSIS OF UNCORRELATED PRIMARY
AND BEACON TARGETS
(JAL-1628, 11 / 17 / 86 AKST)
Approximately 61 minutes of data was extracted from the EARTS CDR
printouts relating to the November 18 incident involving JAL-1628
and the alleged UFO sighting.
Review of the data involving this incident did not show any
abnormalities that could be associated with any type of target as
indicated by the pilot of JAL-1628.
Radar returns from the aircraft and surrounding terrain vary with
the different segments of the flight, but are considered normal
for the area.
Returns relating to the incident can be categorized as three
types: primary radar reinforced by a beacon reply (primary radar
returns and beacon returns are both evident in the same 1/4 mile
range cell), beacon only reply and beacon with an associated
radar reply. Seventy-two percent of the replies were radar with
beacon reinforcement (same range cell) which is normal for the
Murphy dome radar system.
Approximately 25 percent were beacon only and of those that
registered as beacon only, 90 percent of those had a primary only
reply within 1/8 of a mile, either ahead or behind the beacon
target (5 behind, 12 ahead).
Th ese uncorrelated primary returns are not uncommon, due
critical timing associated with the delay adjustments
aircraft transponder for beacon systems and the
correlation circuitry within the radar equipment.
to the
in the
target
Whe n an aircraft is being interrogated as it passes through the
beginning of adjacent range cells the intricate timing between
t h e t wo systems very often is off just enough to declare both a
beacon and a radar target in different range cells, resulting in
uncorrelated radar replies.
Th e data derived from the JAL-1628 flight is representative of
t h e data from another aircraft in the same general area and is
con s i dered normal.
