howdy. Since you're USAF, you may be familiar with John Boyd and his thirty second challenge at Nellis. Col. Boyd was not well liked by Brass, he had no time for pyramid types.
If you know about Boyd's flat plating trick, you may know how stable the HUN was in totally departed flat aspect, all drag, no lift, an object of diminishing energy, giving it up for the 'cause'. It won for Boyd his deserved rep, and cred.
How different is 447's 330? Not much, I think. The a/c derived its 'stability' in deep Stall from spill, not flow.
The HUD, inertial cueing and other military benchmarks are expensive. Very expensive. If Joe Q. Public knew how safe he would be if the beanies spent some dough, he would revolt, as did the Air France pilots, when they finally realized how they had been waltzed by the company v/v PITOT THALES.
It is way important to keep the real deal on the down low, lest profits fall with fewer and fewer fatalities, as equipment is brought (at great expense) into the NOW, out of the THEN.
447 remained stable because she had her airmass controlled. She wasn't "directing" the flow, she was not in flow. She was in "spill". One can fly drag, as well as lift; ask a sailor, or read Boyd's "ACM" white papers.
You speak 'boydese'?
cheers, see you at the bar.
