Ludwig Becker was the best known ace on Dorniers (215B-5) and the "father of early nacht jager tactics", but he was lost flying a Bf110G-4 in 1943 in the short "experiment" of using night fighters vs daylight USAAF raids......
The Dornier 215B had a lot of potential left if it had got the DB605 engine upgrade, and it could carry internal fuel in its bomb bay space unlike the overburdened Bf110G.
