Цитата:Почему никто из 239 человек на борту, включая членов экипажа, не воспользовалься для связи своими мобильными, айнофами, ноутбуками и т.д.?

Вот возможные теории:
According to military radar, the aircraft was flying extremely high shortly after its turn — as much as 45,000 feet, above the certified maximum altitude of 43,100 feet for the Boeing 777-200. It then descended as it crossed Peninsular Malaysia, flying as low as 23,000 feet before moving up to 29,500 feet and cruising there.

Vincent Lau, an electronics professor specializing in wireless communications at Hong Kong University of Science and Technology, said that the altitude might have prevented passengers’ cellphones from connecting to base stations on the ground even if the phones were turned on during the flight or had been left on since departure.
Lam Wong-hing, a wireless communications specialist at the University of Hong Kong, said that cellphones transmit at one watt or less, while base stations typically transmit at 20 watts and sometimes much more. So even if a cellphone showed that it was receiving a signal while aloft, it might not be able to transmit a signal that was strong enough to make a connection, he said.

Investigators do not know if anyone aboard the plane even tried to make a call. Passengers would have quickly become unconscious if the plane depressurized as it soared to an unusually high altitude right after the turnaround, pilots said. Whoever diverted the plane could have disabled the release of oxygen masks. http://www.nytimes.com/2014/03/18/world/....html?_r=0
