A SHOCK "triangular UFO" has been spotted close to a secretive US military base, amid speculation that the aircraft is the mysterious TR-3B on a test-run in Texas.
Incredible footage has captured a bizarre "triangle UFO" flying across the El Paso sky in Texas this week.
The mysterious sighting has been linked to top-secret US technology developed at a nearby military research base.
Online viewers speculated that the aircraft, which has left many baffled, was a TR-3B aircraft, which is part of a "black government project".
Several sightings of "black project" aircrafts have been recorded close to military testing areas, such as Edwards Air Force Base in California, and United States Air Force Plant 42.
The man who filmed the latest footage stopped his car on his way to work to capture the unusual object before it vanished.
The video of the supersonic aircraft has already racked up thousands of views after being posted online.
The man told the Daily Star: ""I stared at the sunrise as usual because I have to stop at a red light, right before I get to work.
"After a few minutes, I glanced to the right and saw a glowing triangle and thought it was weird. So I took several pictures and a short video."
