Indeed, jcj - Rockhound's 'pilot' was talking out of his seat cushion.
Actually he was entirely correct. The 1st step in unusual attitude recovery is to unload the airframe...period. No pilot...let alone "professional" pilot should maintain a particular control input for as long as the PF did. Obviously the trim issue becomes a significant complication and either manual trim or continued full deflection would be required to correct the trim.
Had the PF simply unloaded the airframe the moment the stall warning sounded the entire incident would most likely be one of the dozens of "recoveries" from this malfunction. Only his continued incompetence generated the stall then forced the trim so far out of sorts.
So...in the early stages of the upset the statement is entirely correct...
