DWT This is a forum for professional pilots. if the boys in the back reading this are put off due to not understanding, let them get a job stacking shelves in Tesco where they can speculate from a position of ignorance about the price of bananas at no risk to safety.
However I suspect that most of the boys in the back who are bothering to read this thread, are less stupid than you imply.
Sorry but every time there is a post promoting secrecy on this matter, I will rile against it.
