Mysterious lights 'changing formation' over Dallas

Mesmerising footage shows a series of glowing lights hovering above Texas sparking fears of a possible UFO.

The mysterious lights were spotted changing formation in the night sky over three separate counties across an 80-mile radius.

Stargazers in and around Dallas chimed in with sightings after footage of the bizarre presence over Duncanville, in the south of the city, was shared online.

A flurry of witnesses came forward to claim sightings from multiple sites, with some convinced the lights were caused by visiting aliens.

 Retail manager Javier Estrada III, who filmed the footage, said: "What I saw mesmerised me. I was visiting family for my grandma's birthday and happened to look up.

"I saw glowing lights hovering real slow and that's when I knew it was something out of the ordinary - not scary, just crazy to look at.

"I do believe in extraterrestrials so the first thing that came to mind was a UFO. As soon as I saw it, I was starstruck - it seemed so real.

"I wouldn't mind having aliens come to visit but knowing us in the USA we will probably attack them first."

In Javier's video, four lights are visible in the starry sky, shifting from a kite-like formation to a square one, before drifting apart and out of view.

Two more lights then come into view before the clip ends. They could have been drones.

Sightings were reported from a total eight different areas in and around the city, mainly towards the south, with many describing the lights as forming a "straight line."

Onlookers also reported the phenomenon in Allen, to the north of the city, and Granbury, to the southwest - which are separated by a distance that would take nearly two hours to drive.

And with more than 16,000 people seeing the footage, there were plenty of suggestions as to what the lights could be.

Some suggested the display was caused by drones or Chinese lanterns, but nobody ventured an explanation as to how they were spotted in places so far apart.

Others speculated satellites or weather balloons, though nobody offered any tracking data.
