Taken in 1919, this ghost photo of a RAF squadron from World War One has an extra ghostly face in the picture.
It is believed to be Freddy Jackson, an air mechanic who had been accidentally killed by an airplane propellor two days before the pic was taken.
His funeral took place on the day the photograph was shot.
Members of his air squadron recognised his face with ease and believe he must have showed up for the haunted picture, unaware he had passed.
Freddy’s ghostly apparition appears behind the airman in the top row, fourth from the left.
