Think we are over reacting slightly guys. You do not want to give joe public access to maintenance manuals and the like, for fear he may have evil intentions?
But he can buy Flight international cut-away diagrams and many other such informative publications that would easily give some one with ill-intent enough knowledge to cause havoc...in fact he does not even have to buy them, there are plenty available on the internet.
If such people are set on destruction they will find a way to get what they need.
Sorry gas-man, I am a Boeing operator and do not have any AI info available, but I am sure you will find some.
