Hmm thank for your interesting view which carries much weight.
I note you say
"a light Apache can pull about 3 g's before the rotor stalls, and yet the engines can only produce about 2 or a bit more. I wonder what the G level was of that machine as impact occurred."
Me too!!!!
What coning angle would an Apache make whilst pulling 3G?
We could measure the coning angle from the video and then we'd know !!
Looks like quite high cone to me, about 3 times (ie approx 3g)?
and
"speed can be sacrificed to produce extra thrust. "
well he didn't run out of speed
and as for "running out of climb performance" is concerned ??
he's not even
nearly converting Fuel and Kinetic Energy to Height Energy
and what is you opinion of this one

"I seriously doubt that blade stall produces accidents, mostly it is lack of available maneuverability as limited by engine power."
anyhow thanks for your view,
they'll be delighted !!
get well soon
