Another excerpt from Angle of Attack by Mike Gray:

Like all power-plant engineers, the [NASA] Lewis [Research Center] people labored in obscurity; glory in the airplane business went to the pilot or the builder, and nobody ever remembered the guys who designed the engines that made it all possible. One Lewis engineer, Herman Mark, tells the tale of an aviation banquet he attended shortly after World War II where people were asked to say what they did in the war. As other men talked of dogfights over New Guinea and night raids on Schweinfurt, Mark braced himself for the mortification of admitting that he had never left Cleveland. When his turn came, ge stood, embarrassed, and explained that he had been working on engines out at Lewis during the war and all he had really done was to design a little metal vane that redirected the airflow in the B-29 engines and eliminated overheating in the bottom cylinders. He sat down, and the ripple of applause built to a roar as the audience came to their feet. This happened to be a crowd that could fully appreciate the meaning of the term "engine fire."
