This showed up for me yesterday; I've never heard of him but apparently he analyzes aviation accidents on his channel. His comments regarding the Dallas crash start at about 22:00 mark. TLDW; is he has long felt the idea of CAF's Warbirds on Parade, with its mixed aircraft types and speeds flying in the same small airspace, has always been an accident waiting to happen. He also states the P-63 pilot was following the directions of the air boss to overtake the B-17. Worth the watch, it has overhead diagrams of the flight tracks.
