I'm still going with catastrophic failure of the airframe, either from a bomb or from something the plane was carrying (a la ValuJet Flight 592).
Even if the pilot and crew were incapacitated, passengers still would have been able to get off messages via cell phones or wireless internet unless something large, loud and sudden happened to everyone at the same time.
Anybody know why the transponder even HAS an "on/off" switch controllable from the cockpit?![]()
cmort666 has at least a plausible theory the only one I have heard so far..
Also, if they didn't KNOW that the plane had been hijacked, nobody would call to report it.I don't think cell phones would work unless in range of a cell tower. Also, if the crew was incapacitated due to a loss of pressure the passengers would be also.
