The Messerschmitt Bf 110, was designed in the middle of the thirties. After a relatively convincing start in Poland in September 1939, the performance of the Zerstörer (destroyer) units, declined rapidly with heavy losses, so much so that at the end of the Battle of Britain it was decided to withdraw the Bf 110s from service and cease production. After the failure of its designated successor, the Me 210, the Bf 110 started a second career which was indeed infinitely more glorious since it scored more kills not only than any other Luftwaffe night-fighter but also more than all the aircraft of this type in all the air forces fighting in World War Two.
