'Flight Sergeant Bill Kelly (left) and Flying Officer Osborne sleep between 'sweeps' in the Dispersal Hut at Rochford airfield. Underneath the bed on which they sleep is the station mascot, a dog called Roger. The original caption states that "Like so many of the fighter squadron mascots, Roger belonged to a pilot since reported missing, and has been adopted by the others".
