That's al well and good, but in your case as with Michael's,
we don't really know what the mishap airplane was actually
doing - all that's been given here is a qualitative 'keeping
up.' Michael has extrapolated that to the extreme steady-state
welded-wing example and you have added the semi-steady-
state example of tracking techniques. You and I both know that
real-life 'keeping up', particularly in an ACM-type environment,
is never steady-state, and all the generalizations fall apart in
the specific, particularly when a limit case is experienced.
So...was the failure stress (STRESS, not normal acceleration)
over the spec value on the mishap airplane? The people shooting
down the investigation results should be prepared to answer this...
quantitatively.

If you want this type of result, you will have to wait until the NTSB
releases the investigation reports. Until then, you'll have to make do
with general discussion like the rest of us. I just happen to be in a
link with other pilots who are aware of the failures and have educated
opinions about what's causing them. None of us claim to have direct
answers to these questions. Actually, we are as puzzled as you are as to
why these accidents are happening and exactly what is causing them.
Any opinion I post on issues like the T34 situation is simply based on
my experience flying the airplane and any knowledge I might have
concerning how it should be flown....nothing more....nothing less.
I have no idea what Michael's interest is and don't care.
