A jet was spotted making a perfect spiral out of its contrails in the sky above Los Angeles, California.

Filmed on August 5, an aircraft is seen flying in a circular motion with its contrails forming a perfectly shaped spiral.

The filmer told Newsflare: "Something caught my attention high up in the sky. Initially, I thought it was a cloud before I realized that it was some sort of a jet who had some fun making outward circles way up there.

"It was quite a bizarre experience, I've never seen a jet do this before, maybe they were bored? He continued with about half a circle more before he blasted off in a high speed."
