Why has crew subtle incapacitation or a deliberate malevolent act seemingly been ruled out... when we have no idea at all what was taking place in that cabin, or cockpit.
Deliberate malevolent act ???????????? Like they were muslim fundamuntalists ??????????? This is Air France mate, or is it that France and Egypt are the same to you ???
As to incapacitation, you've got your answer on the post above.
Are you for real ??
