elonmusk909, fred.james48 and a host of other IDs are all the same person, a guy who used to post as waynedickenson941. He may also have posted at one time as dell.george. He doesn't know anything, about commercial A/Ps, Boeing or the aerospace industry and he's a known and proven liar. Pay no attention to anything he posts. It's all garbage. Just ignore him or better yet, use the board's "ignore function" and you won't even see any of his lunatic rantings.
