Boyd also tended to react harshly to anything he saw as waste or foolish spending. Coram's book spends some time on this, including his marathon fights with the Air Force brass regarding aircraft design and what he saw as foolish modifications to sound designs (the F-15 and F-16 spring immediately to mind, but it's also worth remembering that one of his disciples played a major role in designing the A-10). I think it was that side of his personality that attracted followers, too.

Boyd in my mind is rather like Poole...a great synthesizer of ideas from a variety of sources but only original in a handful of cases. Boyd's originality is to my mind greater than Poole's, but they are in many ways similar.
