The Lockheed P-38 was designed with both engines critical with respect to engine out during takeoff unlike current light twins with C/R props. The down blade on both P-38 engines is outboard rather than inboard. Perhaps a number of P-38 pilots would have survived their engine outs had the engine rotation been reversed. What was the intended design advantage? Have any of the remaining P-38's had engine rotation swaps and if so, were there any changes to the flight or ground handling characteristics?
