What is a black triangle UFO?

A “black triangle UFO” is a label for an unexplained object that a witness describes as dark and triangular, often with lights. It is a description, not an identification: the reports in our coverage do not establish what the objects are or whether different sightings involve the same thing. [1][3][6]

The details vary from report to report. Near Kirkland, Washington, on May 13, 2005, one witness described a black triangle with seven salmon-orange lights, seen for 15–20 seconds. [1] In Rouyn-Noranda, Quebec, a witness reported a dark triangle with lights and a low hum, visible for 3–4 seconds; the account’s date is inconsistent, listing June 1 in its summary and June 6 in its description. [3] A driver near Seattle reported a large, silent triangle with moving lights in February 2003; that account is also unverified. [6]

Those are eyewitness reports, not proof of a single kind of craft. Other coverage discusses triangular-object footage and military-related reports, but the descriptions alone do not confirm an origin or explain what was seen. [2][4][5] What remains unknown is whether any particular black-triangle report represents an aircraft, another known object, a misperception, or something not yet identified. [1][3][6]
