The growing importance of the 'electronic war' in the air in 1943 was responsible for the creation of 100 Group RAF. Their task was to fly both defensive and offensive sorties and employ highly secret Radio Counter Measure equipment. The Group flew from airfields at Foulsham, Great Massingham, Little Snoring, Oulton, North Creake, Swannington and West Raynham. The aircraft types flown were the Halifax, Beaufighter, Mosquito, Liberator and Flying Fortress. The Group included 192, 169, 23, 171, 199, 214, 157, 85, 141 and 239 Squadrons. As part of Pen and Sword's Aviation Heritage Trail series, the airfields and interest in this book are concentrated in a particular region - in this case Norfolk. This book looks at the history and personalities associated with each base, what remains today and explores the favourite local wartime haunts where aircrew and ground crew would have sought well-deserved entertainment and relaxation. Museums and other places that are relevant are also described and general directions on how to get them are also included.
