Your argument is getting ridiculous. Your saying no one uses an oxygen mask when the cabin is full of smoke, now your saying it all happened too quick. Of course the transponder was switched off because the evidence says it was switched off before the last transmission, a transmission that did not include any mention of a problem. Frank I have been in a building fire and also in an aircraft that was filled with smoke from a failed engine.
No more from me on this. No one has any idea what happened but some just keep plugging away at there own theory.
