this very well could have flown with no auto pilot inputs at all which would also explain a much further left turn than would have been on auto pilot when it passed the last programmed way-point it would have just continued on the same ground track it was on until it ran out of gas. that's why i think the auto pilot was out. the two things, the pitch changes and the fact that the headings swung around as far down to the southwest as it did, very likely scenario that that could have happened and all communications systems, transponder, radios, acars, if there was some sort of problem with an electrical fire in that center pedestal area or supply for those things that would have been knocked out. which we may very well have had a zombie airplane flying across the country, aka payne stewart's crash. >> bill, i don't think you buy this theory, do you? >> first off i really don't like the term zombie plane. it connotes a sinister as peck to it. i prefer to call it a ghost plane.
