República Democrática del Congo.Kerekere · the fragment of the object that exploded over the Congo (1965)

At some point between 10 and 15 October 1965, near Kerekere, in the north-east of what was then called the Republic of the Congo —today's Democratic Republic of the Congo, not Congo-Brazzaville—, an unidentified flying object "exploded and fell to earth". A ground search recovered a metal fragment. That is all that is known of the event: the report that tells it says that, apart from the object flying east to west, "specific observation and recovery details are lacking". The place name is almost illegible in the surviving copy; the reading "Kerekere" comes from a later CIA memo citing the report, according to the writer Jason Colavito. There is a village of that name in Ituri province, near the border with Uganda.

The fragment ended up with US military analysts —the declassification stamp is the Army's—, who wrote a technical "exploitation report", classified confidential, titled "Fragment, metal, recovered in the Republic of the Congo, origin believed to be an unidentified flying object (country unidentified)". The piece weighed 41 grams, measured about 2.25 by 1.75 by 1.0 inches and had roughly the density of iron. It consisted of six T-shaped fins along its axis, with surfaces rounded and melted by heat. The analysis describes it in detail: a mild-steel core carrying a stack of silicon-steel laminations a quarter of a millimetre thick, copper-plated and diffusion-bonded, with the shaft serrated so the laminations would not slip. The T-shaped fins, the report explains, are used to hold the winding wire in place on high-rpm motors.

There are four conclusions. The fragment was originally part of an electrical component and could be identified as a motor rotor, a generator armature or a similar electrical device. It was made of 0.010-inch silicon-steel laminate on a mild-steel shaft. Materials, processes and dimensions "prevent determination of exact origin (country)". And the surface appearance and microstructure indicate exposure to temperatures above 2,500 °F, about 1,370 °C, with features suggesting the piece was moving at high speed while hot. The report was declassified on 10 February 1992 by the freedom-of-information office of the US Army Intelligence and Security Command (INSCOM), and it is part of the collection of UFO documents published by the NSA.

The report does not say where the object came from, but the space calendar offers candidates. According to Jonathan McDowell's satellite catalogue, several large objects re-entered in those days: on 11 October, the Soviet satellite Proton 1, of more than twelve tonnes, and two US CORONA reconnaissance satellites; on 15 October, the cabin of Korabl-Sputnik 1 (Sputnik 4), the Vostok programme test craft launched in 1960. There is no way to know whether any of them passed over north-eastern Congo at the moment of the sighting, because the report gives neither the exact date nor the time.

It is the corpus's first case in the Congo, and one of the few in which there is a laboratory analysis of a fragment attributed to a UFO, made by an official body and preserved in full. In UFO literature it has been presented as proof that the United States secretly collected the remains of a craft. The document says otherwise: the fragment was part of a motor or generator made with conventional techniques, and the report left open only the question of which country had made it. The phrase "country unidentified" in the title, sometimes read as a mystery, means exactly the opposite: it takes for granted that a country made it.

The context explains US interest better than any exotic hypothesis. In October 1965 north-eastern Congo was a war zone: the Simba rebellion, backed from the Soviet bloc, was being crushed by the central government with mercenaries and with aircraft that the CIA funded and partly crewed. The United States also ran a programme, known as Moon Dust, to recover space-vehicle debris worldwide, above all Soviet, and analyse it. An object that explodes in the sky of that region, with a recovered metal part, was at once possible satellite debris, possible military aircraft debris and a possible piece of enemy technology. That is the question the report answers, and that is why it focuses on the country of origin.

That is why the case weighs mainly on the mundane explanation —a satellite re-entry, with several candidates in those days—, with weight for another state's technology and for an own programme, because the analysts could not tell a Soviet part from an American one or from a piece of a wartime aircraft. The remaining indeterminacy reflects how little is known about the sighting. It belongs to the same family as ↗ and ↗, but with an important difference: there the object carried numbers that allowed it to be identified; here the heat erased everything that might have told where it came from.
