A UFO has been filmed seemingly sucking up the clouds in the sky left behind by an aircraft engine.

This bizarre footage was captured when chemtrails disappeared behind a white light that moved smoothly through them.

And when it was done, the unidentified light or craft just zipped off again.

Posted online by YouTuber WTFflow , the video was taken on September 28 at 7.41pm.

He explains: "I was watching an odd looking light crossing the sky at variable speeds around my house, during the sunset.

"To me it was just some sort of helicopter, or maybe a drone. But after five or 10 minutes, I began suspecting the object not to be manmade.
