(Before It's News)
This photograph was taken in England during World War 2, though no additional information is known about the sighting. From the image, it is clear an object of large size is flying through the sky, and is not similar to any known aircraft at that time. It is also apparent that the photographer intended to snap a photo of this object in the sky, and therefore it is not an artifact made through damage to the original print.
