Also the father of the A-10, which the air force hates but is so useful. He arrived at the design after studying how air power was used in WWII. We still get a lot of utility out of the A-10. The air force is of course trying to kill it still.
Just a guess: the A-10 is designed as a support aircraft for ground troops, which means that if it does its job perfectly, the Army gets to claim a decisive victory. The F-15 is an air-superiority fighter, which means that if it does its job perfectly, the Air Force claims a decisive victory. Inter-service rivalry is a Thing...from the POV of an ordinary citizen, it doesn't matter as long as we whup the bad guys, but from the POV of a career military bureaucrat it matters a lot whether the victory is credited to his branch of the service.
I do, actually; he says it himself in the video. And the F15 didn't start as a multi-purpose fighter; it started as a single-purpose fighter. It was when the bureaucratic process started that the design of the plane changed and arguably ruined the design.
