Quoting Smithsonian National Air and Space Museum | Lockheed P-38J-ten-LO Lightning :
In the P-38 Lockheed engineer Clarence "Kelly" Johnson and his group of designers developed a single of the most profitable twin-engine fighters ever flown by any nation. From 1942 to 1945, U. S. Army Air Forces pilots flew P-38s over Europe, the Mediterranean, and the Pacific, and from the frozen Aleutian Islands to the sun-baked deserts of North Africa. Lightning pilots in the Pacific theater downed far more Japanese aircraft than pilots flying any other Allied warplane.
Maj. Richard I. Bong, America’s top fighter ace, flew this P-38J-10-LO on April 16, 1945, at Wright Field, Ohio, to evaluate an experimental approach of interconnecting the movement of the throttle and propeller manage levers. Even so, his right engine exploded in flight before he could conduct the experiment.

Quoting Smithsonian National Air and Space Museum | Boeing B-29 Superfortress "Enola Gay":
Boeing’s B-29 Superfortress was the most sophisticated propeller-driven bomber of World War II and the initial bomber to house its crew in pressurized compartments. Although made to fight in the European theater, the B-29 found its niche on the other side of the globe. In the Pacific, B-29s delivered a variety of aerial weapons: standard bombs, incendiary bombs, mines, and two nuclear weapons.
On August six, 1945, this Martin-constructed B-29-45-MO dropped the initial atomic weapon employed in combat on Hiroshima, Japan. Three days later, Bockscar (on display at the U.S. Air Force Museum close to Dayton, Ohio) dropped a second atomic bomb on Nagasaki, Japan. Enola Gay flew as the advance weather reconnaissance aircraft that day. A third B-29, The Fantastic Artiste, flew as an observation aircraft on both missions.
