Doolittle was an amazing personality. While the Tokyo Raid may be his most famous exploit, Doolittle was, above all, an engineer. His research into high octane aviation fuels in the 1930s gave American aircraft a significant performance advantage when war finally broke out. He was also a Schneider trophy winning pilot, holder of several air records, performed the first blind landing, etc. As the commander of the 8th Air Force, he changed the mission of VIII Fighter Command from "bringing the bombers home" to "destroy the Luftwaffe". While the bomber crews may have not liked that switch, history proved that Doolittle's strategy was correct and ultimately saved lives.
