A history of the British RAF division in Norfolk dedicated to radio countermeasures during WWII. As part of the AHT series, the airfields and interest in this book are concentrated in a particular area—in this case Norfolk. The growing importance of the 'electronic war' in the air in 1943 caused the creation of 100 Group to fly both defensive and offensive sorties employing highly secret Radio Counter Measure equipment. The Group flew from airfields at Foulsham, Great Massingham, Little Snoring, North Creake, Swannington, and West Raynham. The aircraft flown were Halifax, Beaufighter, Mosquito, and Fortress. The Group included RAF Squadron numbers 192, 169, 23, 171, 199, 214, 157, 85, 141 and 239.100 Group (Bomber Support) looks at the history and personalities associated with each base, and what remains today, exploring the favorite local wartime haunts where aircrew and ground crew would have sought well-deserved entertainment and relaxation. Other museums and places that are relevant will also be described and general directions on how to get them included.
