Have my own notions, but would be interested from a pros viewpoint.

I'm assuming that mechanical was not a factor in any of these, BTW.Might
have been, but it appears that in each case the pilot went in with no
commital gates and no escape route.

Can't say much about the Extra (at least it looked like an Extra) but
the Hurricane and the King Cobra are accidents I've been involved in
with safety discussions within the war bird demonstration community.

To me, the KC accident looked like the result of a way too low energy
state going through the top gate. He should have had at least 150
indicated inverted on top but it looked like he lost his energy to drag
going up the up line by pulling too much g. He was practically dead in
the water on top but apparently at fairly high power. This looked like
it torqued him in roll pretty good and he lost it coming through the
gate. He recovered as the angle of attack narrowed back into the work
range but by then he was committed way too nose low and had no radial g
available to affect the recovery.

The Hurricane looks like it will come down to a simple brain fart. The
guy was very qualified and had experience. So far it looks like he
simply committed to a Split S below his minimum AGL parameter for the
Hurricane. This one is very similar to the Thunderbird F16 accident at
Mountain Home AFB where the team lost a Viper. Brain fart!
