GB "...So, the question: will pulling power to one engine of a big twin in deep stall help?..."
Won't that depend on how the Thrust is "Pointed"? Rudder, Elevator? As I recall, the DC10 that lost (sic) number one on TO had ample airspeed to fly its commanded AoA (By F/O). When the Captain took over flying, He could have reduced thrust on #3, and mitigated the a/c's obsession with rolling (over) to the left. As it was, Thrust was left full, and the a/c had insufficient Yaw authority to prevent its rollover to the left. There is a rumor that Captain's foot slipped a split second on takeover (The Right Foot), allowing a smidge of left Yaw, sufficient to unrecover.
This was at 500AGL on a clear day, with TWO engines left. It would at least seem after all this time that the flight crew (447) were surprised, and possibly unable to pull things together, for reasons we'll soon know.

Beyond a certain threshold, doesn't Thrust (even power to keep 'flying') simply make things worse?
