Conspiracy theorists claim that they’ve spotted an object in the sky that’s physically impossible for humans to build.
A footage has been released showcasing three lights moving in the sky, this has led many to speculate that a spy "TR-3B" type UFO flew over Russia sometime last week.
The video was posted on YouTube channel UFO Today and wrote: “The object is moving at a very slow pace, too slow to be classic airplane.
“The speed at which this object was moving is physically impossible for any airplane build by mankind.
“At a certain point in time the aircraft loses propulsion in one of the three engines, but that does not stop it.
“It continues its way through earth's skies.
“Reports generally describe this class of UFOs as large, silent, black triangular objects hovering or slowly cruising at low altitudes over cities and highways.
“Sightings usually take place at night. These objects are often described as having pulsing coloured lights that appear at each corner of the triangle.”
The conspiracy theorists alleged that the TR-3B is a secret "black project" spy craft of the US Government that can be flown into space. The footage was titled the “best evidence ever” that UFO’s exist.
Irrespective of the claims that were made by the YouTube channel, others have attempted to debunk the video. The author of the UFO Investigator's Manual, Nigel Watson, who wrote the book examining UFO sightings stated that judging the vehicles speed could be harder than the theorist predicted.
Watson said: “At night it is hard to gauge the distance and size of an object or lights, which in turn makes it difficult to judge their speed.
“As this seems to be flying slower than an aircraft I'd say it is a drone with lights on it.
“Drones can hover and move slowly, with little noise.
“So I don't regard this video as evidence for ETs visiting us.”
