The mysterious "Dudley Dorito" UFO has been spotted for the fourth time in five years flying through a cloudless sky over woodland in Yorkshire.
The object, which looks like an extra-terrestrial tortilla chip, was captured by an amateur cameraman who posted the footage on YouTube.
He can be heard saying "I don't know what that is" as the triangular aircraft glides silently across the frame above a forest in the north of England.
