TR-3A and TR-3B: The Infamous Black Triangle

... a friend said he would never forget the sight of the alien looking TR-3B based at Papoose. The pitch black, triangular shaped TR-3B was rarely mentioned, and then, only in hushed whispers at the Groom Lake facility where he worked.

The craft had flown over the Groom Lake runway in complete silence and magically stopped above Area S-4.

It hovered silently in the same position, for some 10 minutes, before gently settling vertically to the tarmac.

At times a corona of silver-blue light glowed around the circumference of the massive TR-3B. The operational model is 600 feet across.

Black triangles are a kind of Unidentified Flying Object (UFO) that have been observed in the skies since the 1970s (and possibly earlier), to the present day.

They have appeared more commonly over cities of the United States, and England, but have been spotted world wide including a mass sighting over St. Petersburg, Russia on February 19, 1997.

Since then, hundreds of observers have reported enormous, totally silent, black triangular craft hovering or slowly cruising at low altitudes over cities and highways, usually at night...

A speech given at the International UFO Congress, in Laughlin, Nevada in 1998 by Edgar Rothschild Fouche, (an engineer who claims to have worked at Area 51), suggests that the Black Triangle is a Top Secret, experimental, U.S. Air Force vehicle known as the TR-3B, code named "Astra."

The TR-3B is supposed to be a 600 foot wide (180 m), triangular aerospace vehicle that utilizes a nuclear reactor to generate an intense magnetic field that negates Earth's gravitational forces on the mass of the vehicle by 89%.

By mid-2004, there were almost 400 separate reports of flying triangles, wedges, or boomerangs clearly visible over densely populated areas and highways, mostly near the East and West Coast of the United States.

This geographic distribution also matches the locations of U.S. Air Force bases, leading to suggestions that the craft either belong to the U.S. Air Force or are investigating Air Force installations.

The remaining possibilities are that they are previously unknown American aircraft, manned or unmanned, which are being deployed in a 'high-visibility' fashion, but without public notice for some reason; that they belong to some nation or organization other than the United States, which wishes to display itself in this fashion; that they are some sort of common error of identification of some 'conventional' aircraft or other phenomenon; however, this could not explain why their observation started only in the 1990s.
