World War II- Part 24-Battle of Britain (July 10-October 31, 1940) Battle of Britain was a major air campaign between the Royal Air Force and Germany's Luftwaffe. The RAF successfully defended their nation greatly outnumbered and prevented a planned German land invasion called, Operation Sea Lion. RAF possessed several advantages including a more advanced radar system, (Dowding System), named after Air Chief Marshall Sir Hugh Downing and superior Spitfire and Hurricanes planes.
