Handing over to the FO to free up a bit of brain-load and he doesn't do the one thing - use the Pickle Switches - that might well have given the clue how to save the aircraft.

An important point. Would the captain be referring to the load while hand flying, or just the spin direction of the manual trim wheel? My highlight.

. . . The purpose of the STS is to return the airplane to a trimmed speed by commanding the stabilizer in a direction opposite the speed change . . .
The speed of course was a bit of electronic guesswork by then.
