RAF WWII Log Book - 214 Squadron
Named original WII RAF log book of Wireless Operto J. Swinburne. Served in 214 Squadron. Many bombing missions over Germany listed - Berlin, Hamburg, etc.
At a time when Stirling losses led to the aircraft being withdrawn from bombing Germany the squadron transferred to RAF Downham Market in December 1943. In January 1944, the squadron was converted to special operations, joining No. 100 Group RAF for electronic countermeasures in support of the main bombing operations.
The squadron used the Boeing Fortress Mk II and Mk III and Stirlings. They used the jamming system codenamed "Airborne Cigar" (ABC) to block German night fighter communications. German speaking radio operators would identify and jam the ground controllers broadcasts and also pose as ground controllers themselves with the intention of steering the night fighters away from the bomber streams. At least some of 214 Squadron's B-17s were equipped with 'Piperack' which countered the Germans' Lichtenstein SN-2 aerial intercept radar.
