Someone call Will Smith and get him on this!

Ok, so it's probably not a UFO. Even a UFO expert The Sun talked to isn't convinced.

However, British UFO expert Russ Kellett isn’t convinced the object is a vessel from another planet.

He said: “It seems to get narrower and wider as it’s moving, it’s hard to say.

“I always send footage to an expert to image enhancement as it looks good but unfortunately it could be anything.

“There should be nothing getting that close to an aircraft. It doesn’t look to be a bird or anything like that but at a different angle it could be anything.

“You can believe in UFOs and be logical about images as well.”

If it's not a UFO (of the alien variety), what is it?!
