Strong evidence: instrumental sensor record + multiple witnesses (typically military). Three independent axes: the «tier» measures the strength of the evidence; the «probability» estimates how genuinely unexplained the case is —a natural phenomenon can remain unexplained, so it does not equal «non-prosaic»—; and the partition of explanations (below) says what it most plausibly was. So a well-documented case can have a possible hoax as its most plausible cause, and a Tier B is not, for that reason, a hoax.

The file in question
The episode is part of a wave of unidentified-aerial-phenomena reports over North Africa in the mid-1970s. In the preceding weeks, Algerian military observers had logged unidentified 'machines' maneuvering in their airspace, with at least one radar contact on March 6, 1975.
The next day, March 7, 1975, Colonel Abdelhamid Latreche, Secretary General of Algeria's Ministry of National Defense, summoned a diplomat from the US embassy in Algiers and formally asked whether the United States could offer any explanation for those objects. Latreche noted that his Ministry had already considered and ruled out the usual conventional explanations —space debris, decaying-orbit satellites, atmospheric optics— before resorting to external consultation. The conversation was recorded in State Department cable 1975ALGIER00638, later declassified and published in the WikiLeaks PlusD archive, and replicated in CIA CREST material on 'UFOs over Morocco and Algeria'.
It is important to read the full cable, not just the Algerian gesture. The US officer described Latreche as a person not given to excitement and the Algerian military establishment as rather sober and matter-of-fact, which reinforced the seriousness of the query. But the US analysis itself leaned toward a mundane explanation: they presumed the Algerian military had seen something real but probably a natural phenomenon that had generated some minor hysteria and a chain of repeated reports. Given the seniority at which the query was made, Washington took it seriously nonetheless.
The regional context reinforces caution. The North African wave culminated on the night of September 18-19, 1976 with a mass sighting over Morocco —documented in cable 1976RABAT05209— that was eventually attributed with high confidence to the reentry of a Soviet rocket body (the 'Soviet space junk that became a Moroccan UFO'). That close analogue shows that, in the same region and era, spectacular and widely-witnessed reports had an identifiable cause. The Algerian government issued no public statement and no closure cable from its side is known, so the 1975 incident remains officially unresolved.

Why this case moved the needle
The case's value is institutional, not evidential. It is one of the few in the corpus where a non-aligned state formally documents, through a verifiable diplomatic channel, that its own Ministry of Defense considered an unidentified aerial phenomenon serious enough to first rule out conventional explanations and then request consultation from a foreign power. Cable 1975ALGIER00638 is a primary source with immediate chain of custody: it is not second-hand testimony, it is the contemporary diplomatic record of the gesture itself.
But an honest reading requires holding two things at once. On one hand, the institutional acknowledgment is real and clear —the corpus records it as a data point about how states process the phenomenon, not as proof of its nature. On the other, the cable's evidence points more to a serious concern than to a confirmed anomaly: the US analyst himself presumed a natural cause, and the analogous Morocco episode of 1976 had an identified explanation (Soviet reentry). The case therefore weighs as an example of state acknowledgment from the Global South, with moderate probability, and not as strong evidence of unconventional technology. Its importance is that it widens the geopolitical map of the phenomenon beyond the West, showing that the pattern of 'taking it seriously through military channels' is not exclusive to the United States or Europe.
