Influental means that it has influence on design of aircraft in the future right??? Me-163...forerunner of the Space Shuttle Ar-234 forerunner of almost every bomber of nowadays He-162 was crap (i must admit) but even though it led the way to single engined jet fighters like the Sabre and Mig-15 (altough i then would have to say Ta-183 wich is the real forfather of the Mig-15).
