RAF Tempsford, Britain’s secret airfield during WW2.

Gibraltar Farm near Sandy Bedfordshire was considered unsuitable for any form of flying because of frequent fog and most of the land being waterlogged but was later considered ideal as a clandestine airfield because German air reconnaissance was liable to reach the same conclusion. To add to the deception lines were painted across the runway which looked like hedgerows from the air, hangers etc looked like rundown farm buildings. The farm became RAF Tempsford and the home of 138 Special Duties squadron which was responsible for transporting and supplying SOE and SIS agents in Europe. Due to the land’s unsuitability crashes were frequent.

Halifax of 138 Squadron cashed on landing due to poor ground conditions.

161 Special Duties Squadron flew single engine Lysander Aircraft and later Hudson’s to transport agents and were responsible for air landings on remote farmland. During the moon period (SD Squadrons needed moonlight to navigate) 161 along with its ground crews were relocated to the fighter station at RAF Tangmere on the south coast. Because this station was almost 200 miles closer to France than Tempsford their aircraft which were also fitted with an extra fuel tank bolted between the undercarriage could fly deeper into France with sufficient fuel to return to Tangmere or divert to another field during an emergency.
