I'm not seeking to contradict anyone but put simply searching for good reason to change my view in a debate. Rudeness certainly will not resolve the issue Genghis. You may well keep in mind a quote attributed to Socrates: "the last act of a loser in an argument is to resort to the tool of slander." which of course if true helps no one.
BPF can of course speak for himself but without seeing or at least having a verifiable quote from the Cessna pamphlet i'm not convinced that Cessna have written the words referred to from the pamphlet. I'm absolutely certain though that BPF is genuine in how he remembers the pamphlet and is simply wishing to make a valuable contribution as am I..
