Democratic Republic of the Congo.Kerekere · a flying object explodes and falls in the Congo

At some point between October 10 and 15, 1965, near Kerekere, in the northeast 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." It does not say who saw the object or how many witnesses there were. 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 U.S. 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 millimeter thick. The laminations were copper-plated and diffusion-bonded, and the shaft was serrated so they would not slip. The T-shaped fins, the report explains, are used to hold the winding wire in place on high-rpm motors.

That the fragment ended up in a military laboratory rather than at NASA matches the division of labor proposed in the Department of Defense's March 1963 revision of the interagency guidelines (a draft that was never signed): fragments "readily identifiable or suspect as coming from vehicles launched from foreign countries" were to be delivered to the Department of Defense "on a priority basis" and, after analysis, "will be placed in the custody of NASA"; the State Department would help acquire those that fell on foreign territory. They are the administrative framework of two years earlier and do not mention the Congo.

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 (quarter-millimeter) 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 does not say where the object came from, but the space calendar offers candidates. According to Jonathan McDowell's satellite catalog (GCAT), several large objects re-entered in those days: on October 11, the Soviet satellite Proton 1, of 8.3 metric tons, and two U.S. CORONA reconnaissance satellites; on October 15, the cabin of Korabl-Sputnik 1 (Sputnik 4), the Vostok program test craft launched in 1960. There is no way to know whether any of them passed over northeastern Congo at the moment of the sighting, because the report gives neither the exact date nor the time.

There is a laboratory analysis of the fragment, 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 U.S. interest. In October 1965 northeastern 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 program, known as Moon Dust, to recover space-vehicle debris worldwide, above all Soviet, and analyze 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.

No source attributes the fragment to any of the re-entries of those days, and of the sighting itself very little is known.
