unconfirmed postulations, but nonetheless also potentially indicative of a flight deck emergency involving a fire. or perhaps a major mechanical failure leading the pilot to first attempt to regain control but then perhaps slowly losing awareness after redirecting for an ATB. the mysterious unexlplained sightings of something going into the SCS by both the Viet Navy and the oil rig worker spring to mind.

no, it only indicates that the coms were knocked out.
