Dozy
Your "15" degrees PITCH UP I believe came from the DFDR, via ins and archive. You know the Pitch attained was not nearly that high, in the initial command post a/p loss. Once maneuvered, there ceased to be a comfortable baseline, and his PITCH was not available via INS, and you have no idea whatever what the cockpit was like, you just don't....No PITCH was ever spoken in the CVR, only "you go up....so go down..." "Am I in climb?" So your reference to a specific PITCH value from the DFDR is completely "out of your seat cushion"....I submit PF's grok of PITCH was never accurate, and from the evidence, there is NO way to know what they saw, or believed......via their instruments....
