In an effort to cope with cables that hang from barrage balloons over England, German bombers are being equipped with a wedge-shaped bumper intended to protect the entire wing span and fuselage. One of these fenders was found intact on a Heinkel bomber forced down in Britain. The Royal Air Force is also experimenting with protective devices, but the British fender is a smaller one designed to cut the cables, and is said to offer less wind resistance than the German version.
