This plane has hybrid engines, more reliable and fuel efficient than the original Pratt and Whitney's. Looking at it, you can't tell the difference. I'm a purist myself, preferring to see the planes restored to exact specs, but in this case, I have to approve of the alteration. It was rare for a B29 to return from a mission with all 4 engines still running - and this was true even without encountering enemy fighters or flak.
