What happened
The men said they heard a low hum and saw a large diamond-shaped object hovering silently. They took cover under trees and took six photographs over about ten minutes, until it climbed vertically and vanished. A jet made several low passes. The MoD's photo analysts identified it as a Harrier, with a faint second Harrier in one frame, but the MoD had no record of Harriers flying there at the time. The men gave prints and negatives to the Daily Record, which passed them to the MoD. The story was never published and the originals disappeared. The MoD's line was that no definite conclusions had been reached about the object. Lindsay kept one print for 32 years. Sheffield Hallam photographic specialist Andrew Robinson found it to be a genuine photograph of a real scene, with no evidence of staging, and noted that the top half of the diamond is not a mirror image of the bottom.
