Ken Fostekew sent these photographs over, from the person who was involved with the equipment installation for Fairey Surveys. Unfortunately his contact details have been lost, but the photographs tell the story. The first two photographs are of G-AZFS, and the others are all of G-AZOH.
Doing a quick search on G-AZOH brought up the attached accident report published on the Government Air Accident Investigation Branch website. Looking at the date, and the pilot details, the pilot was probably Geoff Milsom, who kept the plane under control when a wheel came off after landing at White Waltham. Does anyone have any more details?
