Passenger captures moment a 'UFO' overtakes his plane during take-off from JFK airport

This is the moment a passenger aboard a Virgin Atlantic flight captured what he claims is a 'UFO' overtaking his flight during take-off from New York JFK airport. The footage which was shot on July 7th, shows a peculiar object flying past the plane at high speed.

The object comes behind from the aeroplane's tail, and moves like a bird but it's not a bird. The passenger and some others think the object may be an extraterrestrial craft aka Alien plane. Some don't believe it. See more photos after the cut......
