Video footage has emerged of the moment one man may have captured something he shouldn't while on the way to work.

The anonymous source was driving when he noticed something unusual in the skies above El Paso, Texas.

He pulled out his phone to record, and when he checked it out later he was left stunned by the footage.

It shows what appears to be a triangular-shaped aircraft hovering above him.

The man that filmed it said: "I was on my way to work the morning of August 31, at 6.25 in the morning.

"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."

BIZARRE: Could it be a military black project?

The man posted the clip online yesterday, where it has racked up thousands of hits already.

And some believe he may have found something huge.

"Looks to me like a TR-3B craft with the circles under each corner of the triangle if that makes sense," one viewer claimed.

Another added: "It's probably secret military technology monitoring the skies."

And a third claimed: "Has to be a TR-3B."

The TR-3 Black Manta is the name of a surveillance plane of the United States Air Force, speculated to have been developed under a black project.

It is said to be a supersonic stealth spy plane with a triangular design.

Believers in the programme say it was used during the Gulf War to provide laser designation for Lockheed F-117 Nighthawk bombers.

Just yesterday, one was said to be spotted spying on Australia.

And before that, it was also believed to be seen in Russia.
