The issue of recognizing stall brings up the most important
lesson in this whole discussion:
Can the pilot of the plane recognize the stall? Has he
ever stalled the plane? (Other than that one time with an instructor in
HPAT class?) Does he know the behavior of the plane in the stall?
(Mine drops a wing pretty quickly after a buffet – but it’s not
that big of a deal once you get used to it.)
Regular stall training is an essential part of any training
program. This is even more true in these high performance planes. (Yes
I know it’s scary and slightly risky to practice them. I say it’s
much more risky NOT to practice them though!)

By
all means, five knots below target should alert the pilot. However, my airplane
(320) has very honest warning through the control stick. I don't know how you
could miss the warning the airplane controls transmit to my hands and brain. It
starts with a "tickle" and proceeds to very heavy buffeting prior to
the full stall. If a guy could fly past that and miss the impending stall, I'd
guess that his AOA is way beyond his grasp. I have a "zero" knot
tolerance for slow speed. I like dead on-speed and will accept 1-2 knots fast,
but will correct back to on-speed. Slow is not acceptable -- ADD POWER NOW! I
don't mean an automatic go-around, just very urgent action. If it's really
FUBAR, go-around.
I do have a poor man's AOA of sorts. If I'm on speed, my nose just obscures my
aim point. Anything beyond that is way too slow -- ADD POWER NOW!
I am not bad mouthing AOAs. If my EFIS had a provision for one, I'd buy the
sensor. I do not feel that I'm taking undo risk flying without one though.
Is my plane the only one that shakes before it stalls/snaps? Do our pilots not
recognize what the plane is telling them?

At what point do "we pilots" recognize and recover? When we are
upside down? When we are in a deep stall or when we are 5 knots below our
target speed in the pattern?

just
like mine would do if I didn't know how to recognize and recover

"...upside
down at about 45 degree angle" sure sounds like a full stall with a snap
roll, just like mine would do if I didn't know how to recognize and recover
from the situation before it turned so bad. What else could do it?

Another
article that was circulating said they caught a wing and tumbled on
landing. That just isn't true. They impacted the ground totally
upside down at about 45 degree angle and slid 140'. The impact zone and
debris field was lined up with the runway, so was not a base to final stall spin.
The engine was developing power by the look of the prop blades, all control
surfaces were intact and the flaps were fully deployed and appeared to be down
the same amount. The speedbrakes were slightly deployed the same on
each wing, but I suppose that might have been because of the high
impact. The wings were still attached, and actually the entire airframe
was basically still together. I was at the crash
site (with the NTSB guys) with Joe just after the
accident. The NTSB will release a preliminary report next week.
