Canada.Navy flight 125 · the light that closed on an R5D over the Atlantic (Canada, 1951)

On the night of 9 to 10 February 1951, flight 125 of the US Navy's Air Transport Squadron One (VR-1, based at Naval Air Station Patuxent River, Maryland) was crossing the North Atlantic from Keflavik, Iceland, to Naval Air Station Argentia, Newfoundland. The aircraft was an R5D, the Navy version of the C-54, Bureau Number 56501, and it carried passengers as well as crew. At 00:55 GMT on 10 February (21:25 on the 9th, Newfoundland time) it was at 10,000 feet on an instrument flight plan, on a true heading of about 230°, and the navigator worked out a ground speed of about 120 knots against a 70-knot headwind. Every paper gives the position as 49°50' N, 50°03' W, which Lieutenant Fred W. Kingdon placed about 200 miles northeast of Argentia. The plane commander, Lieutenant (junior grade) A. L. Jones, described clear weather, about 60 miles of visibility and thin stratus at about 4,000 feet.

The Project Blue Book file keeps seven statements signed by the crew and dated the same 10 February. Lieutenant Graham E. Bethune, of the Naval Reserve, was co-pilot and flying from the left seat. He wrote that he saw "a glow of light below the horizon", about 1,000 to 1,500 feet above the water, at two o'clock, under thin scud and some 30 to 40 miles away. After 40 to 50 seconds he alerted Kingdon and asked whether it was a ship lit up or a city, though he knew it could not be a city because they were more than 250 miles out. The two watched it for four or five minutes before telling the others. At first it was a dull yellow; then "its angle of attack changed", its altitude and size grew as though it were doing more than 1,000 miles per hour, and it closed so fast that the first feeling was that they would collide. At that point it looked circular, reddish orange on its perimeter, reversed course, tripled its speed and vanished over the horizon. Bethune added that because of the altitude and the misleading distance over water it was "almost impossible" to estimate size, distance and speed, and as a rough estimate gave at least 300 feet in diameter, over 1,000 miles per hour and a closest approach of 5 miles.

Kingdon, the second plane commander, was in the right seat. According to his memorandum, he saw the light beneath the thin cloud layer, to the right and down at an angle of about 45°; it seemed to lie on the surface and threw a yellowish-orange glare through the cloud deck, and at first he thought of a large ship fully lit. Then the object started ascending through the layer, became very bright and circular, with a glowing yellow-orange ring, and seemed to be on a more or less collision course; when a collision looked possible, it made a 180° turn and disappeared over the horizon. He estimated 200 to 300 feet in diameter and wrote that at night over water it was very hard for him to estimate speed, size or distance.

Jones was in the cabin when the navigator, Lieutenant Noel J. P. Koger, came back for him. On reaching the cockpit he took the plane off autopilot and turned to a true heading of 290° after the object, which left on that same heading and went over the horizon in a very short time. He described it as a huge fiery orange disc seen edge-on, whose centre darkened as it moved away, and wrote that as it crossed the horizon it seemed to go horizontal, with only the trailing edge showing in a "half-moon effect". He guessed well over 1,500 miles per hour and at least 300 feet. At 01:04 GMT he called Gander Tower on VHF to ask whether air traffic control knew of any aircraft at that position; it did not, and it notified the military. After landing at Argentia at 02:40 GMT they were questioned by Captain D. H. Paulsen, from Pepperrell Air Force Base, and Commander Wehmeyer, commanding officer of squadron VP-8.

The other statements add detail. Koger was giving the position at 00:50 when Kingdon pointed out an orange object at 060° relative, or 290° true, that looked like a small village or a ship; in the thirty seconds he watched it, it seemed to him "another demonstration of the northern lights phenomena which occur at that latitude", until the object grew much brighter, took shape and came toward them; his best view was of a circular, bright orange-red disc. Lieutenant John M. Meyer arrived when it was already far away and disappearing over the horizon. He wrote that, "not being too familiar with flying in this particular area", his first impression was "the celestial setting of the moon", with the stratus causing the red glow and the halo, and he noted that he had not seen all that the other pilots saw. Radioman Quentin H. Shriver, asleep in the cabin, saw for a few seconds a round object "with a color of fire". Mechanic Gerald M. Daniels had gone forward to ask whether the pilots wanted coffee; the co-pilot pointed out a light at about two o'clock, "slightly lower than us", which reminded him of an eclipse of the sun about three-quarters total in size, shape and colour, three-quarters of a mile to a mile away and doing at least 520 knots.

Northeast Air Command (NEAC), at Pepperrell, sent two teletypes to Washington the same day. The first summarises that the light was first seen on the surface, like the lights of a city, at an angle of about 45° looking down from the plane; that it approached, grew and took a semicircular shape, and that it was on a true course of about 125° while the plane flew 225°; as it approached it turned almost 180° and disappeared over the horizon "as a small ball". Five officers watched it for seven or eight minutes. The second adds that Gander control had Navy 6501 as the only aircraft in the area and rates the report B-2. The pilots' cable quoted in a headquarters radio note gives a diameter in excess of 400 feet. NEAC intelligence report IR-4-51, dated 12 March, repeats those data, says the difference in size between the first sighting and the final small ball was "at least 100 times", names Kingdon as the first to see the object, says no unusual meteorological activity was known, rules out a comet because the object was between the aircraft and the ocean, notes that the report is unconfirmed by other sources and rates it C-3. That report puts the aircraft at 50°30' W, against the 50°03' of every statement.

Air Materiel Command answered on 20 February. J. J. Rodgers's radio note says that on the information presented it was "impossible to come to definite conclusions", that the matter had been discussed with an astronomer attached to the AMC Graduate Center and that, although a meteor or fireball was possible, the description gave reason to believe the aircrew had seen an unusual northern lights display. Lieutenant Colonel Parrot's memorandum of the same date repeats the conclusion. The record card, on an ATIC Form 329 revised in September 1952 (the last digit is blurred) and therefore filled in later, ticks "Was Astronomical" with "AURORA" written by hand and comments that the consulting astronomer believed it to be an aurora. Among the case pages the PDF also includes the cover of the Project Twinkle final report, dated 27 November 1951, with no text linking it to the flight.

Fifty years later Bethune, by then a retired commander, told a different version at the Disclosure Project conference in Washington on 9 May 2001, according to the transcript reproduced on Patrick Gross's website. About 300 miles from Argentia he saw a glow on the water that turned into "hundreds of circles of white lights"; when they went out, a small yellow halo appeared about 15 miles away and came up to 10,000 feet "in a fraction of a second". He said he disengaged the autopilot and pushed the nose over, that the object reached their altitude and filled everything visible from the cockpit, that people were thrown to the floor with bumps and bruises, and that the object then flew alongside, a dome with a visible coronal discharge. He said a passenger who was a psychiatrist told him it was a flying saucer and added: "I didn't look at it because I don't believe in such things." He asked "Al Jones", whom he calls the other pilot, to say nothing, and Jones answered that he had already called Gander to have it tracked by radar. He said the reports were required of them on their return, at Patuxent River. The same website quotes him saying "We had 31 people on board and a psychiatrist; we all witnessed it", attributes to him that the magnetic compasses spun wildly while the object was near, and says he confirmed in the National Archives a radar track at 1,800 miles per hour, something that appears in no paper of the file.

The case keeps something few have: the contemporaneous account of nearly the whole crew, signed the same day, and the account of one of them half a century later. Comparing them shows how the story changed. In 1951 Bethune mentions no white lights on the water, no one on the floor and no dome; he gives a closest approach of 5 miles and says that judging distance was almost impossible. No paper in the file mentions a radar tracking the object: what Gander reported was that it had no other aircraft in the area, an air traffic control fact. The radar track at 1,800 miles per hour and the spinning compasses appear only in later accounts without a document.

The most detailed explanation was published by Philip J. Klass in "UFOs Explained" (1974), as summarised by Patrick Gross: after reviewing the Blue Book file, he placed the Moon below the horizon and concluded that the crew saw a lunar reflection, a "sub-moon", produced by atmospheric refraction and stratus with ice crystals on the horizon. Gross objects that report IR-4-51 gives visibility from 15 miles to unlimited, that Klass does not explain the collision course and the turn, and a radar track that he himself admits is undocumented. The file also contains the same idea from a witness, Meyer, who arrived at the end and did not know the area well.

A calculation of our own with the ephemerides tests it: at 00:55 GMT, from 49°50' N and 50°03' W, a waxing crescent Moon with 16 % of its disc lit stood at azimuth 278°, about 2.2° below the astronomical horizon. At 10,000 feet the sea horizon lies about 1.8° down, and refraction lifts the Moon a little more, so the Moon's upper limb dipped below the sea at around 00:57 or 00:58, about 12° from the 290° bearing on which the crew placed the object and along which they watched it vanish. A low Moon looks reddened and distorted through haze and stratus; Jones described a "half-moon effect", Daniels a sun three-quarters eclipsed and slightly lower than the plane, and the NEAC teletype a semicircular shape. This reading accounts for the time, the direction, the colour, the shape and the disappearance over the horizon.

What it does not account for is the motion the pilots described. Kingdon and Bethune saw the light below them, at an angle of about 45° according to Kingdon and the NEAC teletype, and saw it climb through the clouds, close to within a few miles and turn 180° before speeding away; the teletype and report IR-4-51 say it vanished "as a small ball", with a difference in size of "at least 100 times". For it to be the Moon, the approach would have to be an illusion of light and cloud, which the file gives no way to check. The AMC astronomer's aurora has in its favour Koger's first impression and a geomagnetic Kp index between 4 and nearly 5 that night in the GFZ Potsdam record, consistent with aurora over Newfoundland; against it, every statement describes a circular object and none mentions arcs or curtains. A meteor fits poorly with seven or eight minutes of observation.

No source of the time gives an explanation that covers every account, and none of the documents adds an instrumental record. What the file does leave is a precise timeline, with time, position and heading, and seven testimonies from a single crew that agree on the time and direction but not on distance, size or speed, which range from 520 knots to more than 1,500 miles per hour and from 200 to more than 400 feet. The 2001 version, with its radar, its dome and its injured passengers, adds details that appear in none of the 1951 papers.
