Colin Mitchell of Wilsford Lane, Ancaster, was taking pictures of the Roman Festival on his digital camera but didn't spot the sky craft at first.

It was only when he got home that he and his wife Elaine saw the mysterious object in their picture hovering over houses.

Elaine said: "We just noticed it when we came to look at the picture but we have no idea what it was.

"Maybe someone else can tell us what it might have been."
