Well, uhm, excuse me ladies and gentlemen, I know I probably failed the quiz, but this is why I turn wrenches. So I don't deal with the PAX with a wise crack. If someone is on the plane reading about how to make a bomb, what's to say he is ready to construct a bomb on the plane? What about the schmoe reading the tabloids where the werewolf is doing it to the Queen of England? I mean, don't you think this paranoia has gone kind of ridiculous far? If this book becomes ILLEGAL to read in the plane, then I would do something, but if pax get disturbed over a bomb making book, they are probably the same ones that freek when the plane starts to take off. I can think of alot of other pain in the butt instances besides some nerd trying to get a rise by reading a bomb making book. But there is one rule here we didn't mention. The FA is like the Captain of a ship back there and you must obey the lady (or guy) or suffer the consequences.
