After a Pentagon UAP whistleblower came forward with claims that the United States and other nations have secretly recovered craft of non-human origin, now seems like the time to dive back into longstanding rumors that the United States is operating a secret fleet of large, black triangle-shaped aircraft known among the conspiracy-minded as the TR-3B.

This will be a multi-part series. In Part 1, we discuss reports of Black Triangle UFO/UAP sightings, including Alex Hollings' personal sighting from when he was a child.
