UAP / UFO // Triangle

Triangle

Black triangular craft, often silent and slow-moving, with lights at three or more points. The single most-reported UAP form of the past forty years.

ALSO KNOWN AS: Black Triangle · TR-3B

Triangular UAP reports cluster from the 1980s onward, including the Belgian Wave (1989-1990) and Phoenix Lights (1997). The form has been speculatively attributed to classified US military aircraft.

The black triangle is the most-reported UAP form of the past four decades: a large, dark, often silent craft moving slowly at low altitude, carrying a light at each corner and sometimes one at the centre. Its reporting cluster begins in the 1980s. The Belgian Wave of 1989-1990 supplies the best-documented body of accounts, including reports filed by Eupen gendarmerie officers and thousands of civilian sightings, though the wave’s most famous photograph was years later admitted to be a hoax — a caution we keep attached to it.

The form’s prominence invites a strong conventional reading, and in at least one celebrated instance that reading holds. The Phoenix Lights of March 1997 involved two distinct events; the later portion was convincingly explained as a flare drop by Maryland Air National Guard aircraft, and we record that explanation as well-supported. The persistent triangular appearance of formation lights, and the speculative attribution of the shape to classified aircraft such as the rumoured “TR-3B,” both belong in any honest account.

What keeps the triangle in the file is volume and consistency across regions rather than any single radar-confirmed case. Most reports are multi- or single-witness ground observations, placing the class in the middle and lower tiers of our hierarchy. We weigh each on its documentation, not its drama.
