The Black Triangle UFO Phenomenon: Thousands of Cases, No Explanation
The black triangle UFO phenomenon refers to a recurring category of unidentified aerial craft reported worldwide, with thousands of documented cases spanning from the 1950s to the present day.
Narration
Massive and silent, a dark triangle hangs motionless over America.
From the 1950s onward, thousands of identical sightings were logged worldwide.
Civilians and military personnel stood frozen, watching the impossible craft overhead.
Football-field-sized and utterly silent, the triangle descended low over populated streets.
Researcher David Marler uncovered seventeen thousand case files with still no explanation.
Without a sound or trace, the triangle ascended and vanished into darkness.
