Haywood Hansell said what is probably the most important and ignored thing anybody has ever said about the (then still emerging) U.S. Air Force: "It must be admitted that at least in some very small measure we may possibly have overstated our powers and understated our limitations."
Hansell is probably the most important but overlooked officer in the telling of air force history.
Perhaps the most important and telling thing this biography has to say about him is: "American strategic bombing doctrine had always maintained that industrial and military installations would be the targets, not civilians. In 1945 this long-held doctrine was suddenly abandoned, and Hansell was the only Air Force officer who forcefully opposed area attacks on cities. This opposition cost him his career."
