This creepy photo, taken in 1919, was first published in 1975, by Sir Victor Goddard, a retired R.A.F. officer. The photo is a group portrait of Goddard’s squadron, which had served in World War I, aboard the HMS Daedalus. An extra ghostly face appears in the photo. At the back of the airman positioned on the top row, fourth from the left, can clearly be seen the face of another man. It is said to be the face of Freddy Jackson, an air mechanic who had been accidentally killed by an airplane propeller two days earlier. His funeral had taken place on the day this photograph was snapped. Members of the squadron easily recognized the face as Jackson’s. It has been suggested that Jackson, unaware of his death, decided to show up for the group photo. In case you don’t notice the ghost – look behind the head in the inset on the left of the picture.
