No one had their Cell Phone on?? (There’s always someone...)
No one did any last minute texts??
Cell phone range is only a few miles
Ever try to get a cell signal at 35,000 ft traveling at 535 mph over the ocean?
Better source of information would be the data messages automatically transmitted by modern airliners to their operator’s maintenance base. The Air France Airbus that went down over the south Atlantic was transmitting automatic updates almost until the moment it hit the water. Those messages are already in the database...naturally, the Malaysian airline is not discussing them.
