Dad flew B-17s with the single row 9 cylinder Wright Cyclone radial- - - -1200 HP at max turbo boost, I believe. He called them "Wright Oil Slingers", but they could take lots of battle damage and keep on running.

One of his mechanics during the 1950s worked on B-29s in the Pacific with a way underpowered, very sophisticated radial- - - -he said very few of them returned form Japan with all the engines running, and even fewer made another mission without changing at least one engine.
