A common sound at fighter airfields in England in 1940 was the ringing of the ‘scramble’ bell. This was rung when incoming Luftwaffe (German Air Force) raids were identified by ground-based radar stations. The pilots then ran to their aircraft and got airborne as quickly as possible to attack the approaching fighters and bombers.
