IF there was an aeronautical mount rushmore, Wilbur, Orville, Charles Lindbergh and James Doolittle would be on it.
Doolittle would not be there, he never designed an airplane nor did he make any major advancements in aero engineering.
I would add Clarence "Kelly" Johnson to the group. (Lockheed Electra, F-104, P-38, Constellation, F-80, U-2, SR-71, F-117 and the C-130.)
