The Boianai Mission Disc: Father William Gill and the Sightings of 26 to 28 June 1959

On the evening of Friday 26 June 1959, at the Anglican mission station at Boianai on the south coast of Goodenough Bay, in what was then the Australian-administered Territory of Papua, the head of the mission stepped out of the mission house and looked at the north-western sky. The time was about 6:45 PM local. The witness was Father William Booth Gill, born in Australia on 5 January 1928, ordained in Queensland in 1950, in Papua since 1948, then aged 31. What he reported seeing was a bright white light approaching the station from the direction of the sea.

He called Stephen Gill Moi, a Papuan teacher and teacher-evangelist at the mission. Moi confirmed the light. As they watched, in Gill’s compiled account, the light resolved into a large solid disc with a wider lower deck and a narrower upper deck, four legs underneath, four glowing panels or “portholes” along the side, and at intervals a shaft of blue light directed upward at about 45 degrees. The estimated height was around 100 metres above the mission; the estimated size was approximately that of a five-shilling coin held at arm’s length. Word spread across the station and about 38 people gathered to watch. Across roughly four hours the object descended periodically below cloud and rose above it, and was joined at intervals by smaller objects. Four humanoid figures appeared on the upper deck, bending and raising their arms. Observation continued until about 10:50 PM, when heavy rain shut it down.

The case has stood as one of the most documentary-rich UAP cases on record for 66 years. What did Gill and the mission community see over those three nights, and why has no later reading of the record settled the question?

The mission and the witness

Boianai was a station of the Anglican Diocese of New Guinea, centred at Dogura. In 1959 the bishop was Sir Philip N.W. Strong, who held the see from 1936 to 1962, with David Hand as coadjutor bishop. Boianai itself sat on the southern shore of Goodenough Bay, a known anchorage on the Papuan coast.

The Rev. William Booth Gill, Australian-born, had been in Papua New Guinea since 1948, initially as a teacher, and was ordained in Queensland in 1950. By June 1959 he was the head of the Boianai mission. He wore corrective glasses, which (as Fred Beckman later confirmed for Hynek) were properly corrected on the nights in question.

The named co-witnesses recur across the secondary literature. Stephen Gill Moi was a Papuan teacher-evangelist at Boianai, not a deputy in any ecclesiastical sense, and carried the surname “Gill” by adoption rather than blood. Ananias Rarata was a Papuan teacher at the mission. Annie Laurie Borewa was a Papuan medical assistant and the first witness on the second night. Mrs. Nessie Moi was a mission resident. Eric Kodawara was a youth at the mission.

Boianai did not sit alone. Norman Cruttwell’s 1960 compilation records dozens of UFO reports across Papua in 1958 and 1959. The 26 June event was the centre of a broader 1958 to 1959 Papuan reporting cluster, not an isolated occurrence. Stephen Gill Moi himself had reported a disc-shaped object on 21 June 1959, five days before the main sighting.

27 June 1959

The second night opened around 6:00 PM, when Annie Laurie Borewa spotted the large disc again and called Father Gill. Gill came out about 6:02 PM and, in his compiled statement, confirmed it. Two smaller objects were also visible at intervals.

At about 6:25 PM, in Gill’s account, four figures were again visible on the upper deck. Gill raised an arm and waved. One figure waved back. Ananias Rarata then waved with both arms, and all four figures appeared to wave back. Gill sent Eric Kodawara to fetch a torch and directed long-dash flashes at the object; the witnesses recorded the object responding with wavering pendulum-like motions.

At about 6:30 PM the object had moved and the activity tapered. Gill and others then went in for dinner. This detail is recorded plainly in Gill’s own statement and later becomes a load-bearing point in Philip J. Klass’s critique, addressed below.

Between roughly 7:00 PM and 7:45 PM the object was still visible at intervals. Mission staff went to church for evensong at 7:00 PM. At about 10:40 PM a loud bang or explosion was reported near the mission house. The cause was not established.

28 June 1959

The third night is the thinnest of the three and is rarely treated in detail in the secondary literature. The reported elements are diffuse: a sequence of lesser sightings (including, per some sources, eight smaller objects at about 6:45 PM), and a loud bang on the mission house roof at about 11:20 PM. No structured close-range observation comparable to the first two nights is reported for the 28th.

Gill’s written account and the chain to the RAAF

The day before the first sighting, Gill had written to Rev. David Durie at St Aidan’s College, Dogura, a letter dismissive of UFO claims. On 27 June, after the first night, he wrote to Durie again, telling him that he had changed his views somewhat. (The verbatim wording recurs across the secondary literature and is attributed to Cruttwell’s 1960 compilation; the exact phrasing is treated here as paraphrase pending primary confirmation.)

Gill subsequently prepared a formal typed report. In the proponent secondary literature it runs to approximately eight foolscap pages, separate from the signed witness statements; the “25-page” figure that has circulated elsewhere does not appear in those accounts. Approximately 25 of the roughly 38 witnesses signed. The report passed through the mission chain (Bishop Strong, Bishop Hand). Norman E.G. Cruttwell, an Anglican priest at the Menapi mission in northern Milne Bay and an active UFO researcher, gathered Gill’s report alongside his own collection of Papuan UFO reports.

The case reached the Royal Australian Air Force through a civilian channel, not through the church. On 12 September 1959 Peter Norris, of the Victorian Flying Saucer Research Society, wrote to the RAAF’s Directorate of Air Force Intelligence (DAFI), bringing the Gill case to official attention nearly three months after the event. Civilian groups distributed copies of the Gill report to members of the House of Representatives. On 24 November 1959 the Liberal MP E.D. Cash asked the Minister for Air, F.M. Osborne, in Parliament about the departmental investigation. (The Hansard reference is plausible per the secondary literature and pending primary confirmation.)

The RAAF investigation

On 29 December 1959, six months after the sighting, Squadron Leader F.A. Lang, of AI1 at DAFI, and another RAAF officer interviewed Father Gill. Lang’s written conclusion, as transcribed by Bill Chalker from the file, reads in substance that although Gill could be regarded as a reliable observer, the June and July incidents could have been nothing more than natural phenomena coloured by past events and the subconscious influences of UFO enthusiasts. Lang attributed the lights to the planets Jupiter, Saturn, and Mars seen through fast-moving cloud, with light refraction. (The exact wording is treated here as paraphrase pending primary confirmation against the file.)

Lang’s report did not interview the Papuan co-witnesses. His planets-through-cloud reading does not account for the sustained apparent size of the primary object over hours. The RAAF file is now held in the National Archives of Australia, in the umbrella series A703 and A9755 holding Department of Air UFO records; the precise item reference for the Boianai file is not pinned down in the readable secondary record.

The case in the literature

In 1960 Cruttwell circulated Flying Saucers Over Papua: A Report on Papuan Unidentified Flying Objects, approximately 45 pages, limited distribution, with no commercial publisher. It was later reprinted in Flying Saucer Review, Special Issue No. 4, August 1971.

In 1972 J. Allen Hynek published The UFO Experience: A Scientific Inquiry with Henry Regnery in Chicago, and classed Boianai as a Close Encounter of the Third Kind (CE3). In 1973 Hynek travelled to Australia and Papua New Guinea with Cruttwell. They located six of the original witnesses, all of whom corroborated Gill’s account on direction, manner of approach, and behaviour. Fred Beckman, Hynek’s colleague, separately confirmed that Gill had been wearing properly corrected glasses on the nights in question and that Gill had identified Venus separately during the observation.

From 1974 onward the skeptical literature divided into two distinct strands. Donald Menzel, the Harvard astronomer, advanced a Venus-plus-myopia-plus-astigmatism reading. Robert Sheaffer, in The UFO Verdict: Examining the Evidence (Prometheus, 1981), built on Menzel and elaborated the case for misidentification. Philip J. Klass, in UFOs Explained (Random House, 1974), took a different line. He read the case as a hoax, on the ground that no observer who really believed an alien craft was hovering nearby would walk in to dinner.

In 1996 Bill Chalker published The Oz Files: The Australian UFO Story (Duffy & Snellgrove, Sydney), drawing on the RAAF file (which Chalker accessed in 1982). Chalker argued the Air Force’s natural-phenomena reading was unsatisfactory. In 2013 Martin Kottmeyer, in Magonia’s “Gill Again”, proposed the squid-fishing-boat hypothesis: that the object was a brilliantly lit Pacific squid vessel with masthead lamps, seen at sea against an indistinct horizon and on the underside of cloud.

Hypotheses

All items below are hypotheses, not conclusions. None is endorsed.

A. A genuine unidentified flying object (Hynek 1972 CE3 classification; Cruttwell 1960 sympathetic primary). For: an unusually large witness group; a literate sober principal observer; a contemporaneous written record with co-signatures; a consistent reciprocal-wave detail; six witnesses re-interviewed in 1973 who corroborated direction and manner; the primary object’s sustained apparent size and stationary cloud-base position over hours; no claim of fraud or hallucination that has held. Against: no photographs; no instrument record; the principal who compiled the report was himself the central witness; the mission community had been primed by Moi’s 21 June sighting; the observations were at night, at distance, against cloud.

B. Astronomical misidentification (Menzel 1963; Sheaffer 1981; Lang RAAF). For: Venus was a brilliant evening object in the Papuan sky in late June 1959 and is the most misidentified UFO source in the literature; Lang attributed the lights to Jupiter, Saturn, and Mars through fast-moving cloud. Against: Gill independently identified Venus to Hynek on the 1973 visit, alongside the recalled position of the primary object; Gill was wearing corrective glasses (per Beckman and Hynek); Allan Hendry concluded that a Venus-plus-distortion reading would require distortions of an extraordinary, non-routine kind; the described angular size and sustained position do not match Venus’s apparent diameter or motion.

C. Cloud or atmospheric phenomena. For: sustained low-cloud cover on both nights; cloud-base illumination from an unknown light source could account for the halo beneath the object. Against: the structured shape, with four legs, four panels, and figures on the upper deck, is not easily produced by cloud lighting alone.

D. High-altitude aircraft or balloon. For: the late-1950s Pacific did see high-altitude US reconnaissance balloons and aircraft. Against: the reported low altitude of around 100 metres, the four-hour duration of slow drift over a single station, the deck-level figures, and the reciprocal motion do not match any plausible aircraft or balloon profile.

E. Mass observer suggestion or shared misperception. For: the mission community had been primed five days earlier by Moi’s report; Father Gill was the principal authority figure on station; mission staff went in to dinner and to evensong during the sighting. Against: none of the witnesses recanted; Hynek’s 1973 re-interviews of six witnesses corroborated direction and manner; the report has internal physical consistency across many independent statements written within hours.

F. A real prosaic stimulus plus cloud plus expectation (Kottmeyer 2013 squid-boat hypothesis). For: the most economical combination reading, with a brilliantly lit Pacific squid-fishing vessel as the real stimulus and cloud as back-projection. Against: Boianai sits on Goodenough Bay, a known anchorage where in 1959 fishing vessels would have been recognisable, and no witness then or in 1973 ever proposed “it was a ship” as a possibility, even when prompted.

What remains unknown

The exact wording of Squadron Leader Lang’s conclusion in the RAAF file, and the precise NAA item reference where the file sits today, are not pinned down in the readable secondary record. Neither is the full text of Gill’s compiled report and the signed witness statements, nor how many pages the typed report and the statements together really run to. It is also not established whether any Australian or PNG newspaper in 1959 ran firsthand interviews with the Papuan witnesses independently of Gill, nor whether any 1959 Australian or US military record places an aircraft, balloon, or vessel in the Goodenough Bay area on the nights of 26 to 28 June 1959. The case has stood for 66 years as documentary-rich, multiply-corroborated, and officially classed by Hynek as a CE3, with no skeptical reading carrying the field. What was seen and recorded over those three nights is still not settled.
