Seriously?
Let me explain why I think this is ridiculous.
The P-63 pilot: Craig Hutain, 35,000 pilot, airline pilot, I believe had an aerobatics card from the the FAA since he did the aerobatic routine in the P-63 last year. Not exactly a hot dog. Flew a pretty precise and disciplined Tora show immediately before switching to the P-63.

His mistake was not cowboy-ish, but actually most likely looking ahead and trying to carefully roll out on the same line he’d flown earlier in the Tora “Hawk” following the P-51C ahead. He's going to get the lion's share of the blame, but he wasn't being a cowboy, OR a hot-dog.
The fighter flight also had a fairly well-known safety advocate and respected instructor who is extremely safety-conscious and probably kicking himself right now who was in the P-51C. The bombers’ pilots, several of whom I know, are not exactly cowboys in any sense of the word, nor were they flying cowboy-ish, AT ALL.
The Occam’s Razor issue and most likely cause here is that the two formations got mis-timed, badly, and the pilots were disciplined enough to their formation and show-lines
because they
trusted the air boss too much. That’s hardly cowboy stuff, if anything, it’s complacency caused by multiple successes of flying boring racetracks and believing in the timing ability of the coordinator. It's like a music conductor telling the strings section to come in a bar too early, and the following out of habit, causing an ensuing discordant note.
Regarding coming down on people - nope, not that either. The timing was bad, but the show line airshow rules generally worked. The energy of the B-17 took it straight ahead 1000’ away from the CAF HQ but not pointed at any non-participants.
Look, I'm as upset about this as anyone. Guys I knew died in front of me and my kids, at my home base, and I see the scene every time I go downstairs from my office, but we need to address the primary and secondary causes, and fix those, which means we need to get down to the actual problems, not silly assumptions that don't stand up to scrutiny.
