Thanks matkat - that's essentially what I thought. I had thought that someone here may be familiar with the format of the AMM in use, and commented if there was anything about it that was obviously incorrect. Our own tech pubs (military) are in a different format.
yamaha - I gave details of what it was and where it was from so that anyone commenting would be fully informed. I simply asked if it looked authentic. I did not ask for peoples opinions on 9/11, or the significance of the document; in fact I specifically said "(regardless of what it proves or doesn't prove)".
I thought - perhaps stupidly - that there might be someone in this sub-forum who was familiar with the AMM in question and could comment on it.
I do not have any "ulterior motive".
So, with the sweetest of smiles upon my face - up yours, fella.
