I certainly agree that the pitch input was separate from the roll inputs, and always have. What I do question is whether the intention was conscious or sub-conscious.
How do you reconcile the PF saying that he had been "stick back all the while" with a subconscious action. Surely his words explicitly state that PF intentionally stick backed as soon as he took control initiating the zoom climb.
IMHO one can question why he chose to stick back as a response to UAS however it is without doubt that it was intentional. I think an earlier poster suggested that his arm must have been aching with that continual pull pressure on the side stick. Maybe thats why he eased off momentarily a couple of times.
