Hurri got most kills during the BoB and was the real workhorse. OK, tracer fire is not done too well so I will delete it.
https://secure.wikimedia.org/wikipedia/en/wiki/Boulton_Paul_DefiantThe Boulton Paul Defiant was a British fighter aircraft and bomber interceptor used early in the Second World War. The Defiant was designed and built by Boulton Paul Aircraft as a "turret fighter" and served with the Royal Air Force (RAF). It was a contemporary of the Royal Navy's Blackburn Roc. The concept of a turret fighter was similar to that of the First World War-era Bristol Fighter. In practice, the Defiant was found to be vulnerable to the Luftwaffe's more agile, single-seat Messerschmitt Bf 109 fighters; crucially, the Defiant did not have any forward-firing guns.
It was later used as a night fighter before it was supplanted in that role by the Bristol Beaufighter and de Havilland Mosquito. The Defiant found use in gunnery training, target towing, ECM and air-sea rescue. Among RAF pilots, it had the nickname "Daffy", probably a diminutive of the word "Defiant".
