PNG Air Niugini Radar Contact, January 1985

Brief

On January 28, 1985, the U.S. Embassy in Port Moresby forwarded to USCINCPAC an informal inquiry from PNG's National Intelligence Organization about multiple sightings of high-altitude, high-speed aircraft over Papua New Guinea on the evening of January 24. The NIO's most credible source was an Air Niugini commercial pilot whose airborne radar detected aircraft flying south to north at high altitude and speed near Angoram. Visual sightings from multiple points across PNG included a single contrail moving north to south at 1900 local and a formation of six to eight aircraft traveling south to north at 2200 local. The Embassy, consulting its own records and the 43rd Strategic Wing at Anderson AFB, Guam, told the NIO no U.S. aircraft — specifically no B-52s — were in PNG airspace that night, and requested USCINCPAC confirm the denial.

Key points

• PNG's National Intelligence Organization formally inquired with the U.S. Embassy about high-altitude, high-speed aircraft sightings on the evening of January 24, 1985.p.1
• Residents in Wewak were frightened by overflights to a degree that prompted the provincial premier to call a public meeting, which the Prime Minister attended.p.1
• An Air Niugini commercial pilot's airborne radar detected aircraft flying south to north at high altitude and high speed near Angoram, at approximately 4°S, 144°E — the report the NIO considered most credible.p.2
• Visual sightings from multiple locations across PNG included one aircraft moving north to south at 1900 local and six to eight aircraft traveling south to north at 2200 local.p.2
• The Embassy explicitly denied U.S. involvement, telling the NIO it knew of no B-52 overflights and no U.S. aircraft in PNG airspace on January 24, based on internal records and a phone call with the 43rd Strategic Wing.p.2
• The Embassy characterized the sighting information as 'very sketchy' and noted sources were unsure of the directions the aircraft were traveling.p.2
• The cable was transmitted at IMMEDIATE precedence to both USCINCPAC at Honolulu and the 43rd Strategic Wing at Anderson AFB, Guam, with info copies to State Department EAP and PM/RSA bureaus.p.1

Verbatim

• MATTER CAME TO NIO'S ATTENTION WHEN ITS OFFICER IN WEWAK REPORTED LOCAL RESIDENTS HAD BEEN FRIGHTENED BY OVERFLIGHTS, WHICH LED TO THE PROVINCIAL PREMIER'S CALLING OF A PUBLIC MEETING ON THE SUBJECT ATTENDED BY THE PRIME MINISTER WHO WAS WEEKENDING IN HIS ELECTORAL DISTRICT.

  p.1

• THE REPORT IN WHICH NIO PLACES SOME CREDENCE ORIGINATED WITH AN AIR NIUGINI PILOT WHO HAD JUST TAKEN OFF FROM WEWAK ENROUTE PORT MORESBY.

  p.2

• BASED ON OUR RECORDS AND TELCON WITH 43SW, WE HAVE TOLD NIO WE KNEW OF NO B-52 OVERFLIGHTS AND NO U.S. AIRCRAFT IN PNG AIRSPACE ON JANUARY 24.

  p.2

• ALTHOUGH INFORMATION PROVIDED US ON THESE SIGHTINGS IS VERY SKETCHY AND SOURCES WERE UNSURE OF THE DIRECTIONS IN WHICH AIRCRAFT WERE FLYING, WE WOULD MOST APPRECIATE CONFIRMATION OF PARA 3 ABOVE AND ANY LIGHT YOU MIGHT THROW ON THESE REPORTS.

  p.2

Most interesting

• The sighting event generated direct political visibility at the highest level of PNG government: the sitting Prime Minister attended a provincial public meeting specifically about the overflights.
• The NIO singled out the Air Niugini pilot's radar contact as the report meriting credence, implicitly discounting the purely visual accounts — an unusual analytical step for a brief informal inquiry.
• The Embassy's denial specifically named B-52s by aircraft type, suggesting the PNG side had already formed a suspicion about what platform might be involved before the Embassy's response.
• The cable was routed to State's PM/RSA (Political-Military/Regional Security Affairs) bureau alongside EAP, indicating early awareness that the matter had potential military-diplomatic implications beyond a routine airspace inquiry.
• Six to eight objects were reportedly observed traveling in formation, which — if accurate — would be inconsistent with both a single reconnaissance aircraft and with most conventional explanations.
