Yes and no, the speeds aren't that high (160-170 KTS ground speed at near sea level), the initial pitch change is from +2500 to -1700 ft/min in just 4 seconds. Please note, this is from climbing to descending, implying a negative (or at least a very small but still positive) G. And just a couple of seconds later the VS goes to -4000 ft/min in just 2 seconds or so.
The P-51 shows all over the descent track, a moderate -650 ft/min.
So, yeah, a huge difference between the P-51 and P-63, especially for a "tame" ward bird display, that close to the ground and watching public.
In itself, these items can happen and are manageable, though given the P-63's need to resolve the P-51 prox, the subsequent steep dive and the chosen track "direct" to the display entry point, shows the pilot being behind the aircraft with his actions (IE insufficient real-time insight in the consequences of the choices). That -4000 ft/min should simply never have happened.
