I think I've stayed on track and the one overiding factor common to all is that despite many "experts" on aircraft systems and engineering there seems to be a plethora of "conclusively proved" items that turn out to be absolutely wrong and "impossibilities" that turn out to be anything but.
In threads like this you have to read much deeper than individual posts. While I'll admit that the obvious hunches do vary and are discarded along the way as available evidence surfaces, only as ignorance would one profess a conclusively proven point before the final report of facts and analysis is presented. In almost al cases, portions of the postulations of causes have arguments of pro and cons in their consideration, and it is those arguments that become the basis for the support of readership of these threads.
I suggest that you do not assign words like "conclusively proven", "absolutely wrong" or "impossibility" to postulations within these type of discussion threads.
