Why No Cellphone Calls From Missing Plane?
There have been no calls, no postings on social media, no nothing. In this day and age why?
The apparent absence of any word from the aircraft in an era of nearly ubiquitous mobile communications has prompted considerable debate among pilots, telecommunications specialists and others. Most of the people aboard the plane were from Malaysia or China, two countries where mobile phone use is extremely prevalent, especially among affluent citizens who take international flights.
Some theorize the silence signifies that the plane was flying too high for personal electronic devices to be used. Others wonder whether people aboard the flight even tried to make calls or send messages…
Many aircraft carry satellite phones, and the Malaysia Airlines jet was equipped with them in business class. The plane continued to send satellite pings for nearly seven hours after it was apparently diverted.
But the satellite phones are part of an aircraft’s in-flight entertainment system. If someone deliberately diverted a plane and turned off its transponder and other communications equipment, that person is likely to have disabled the in-flight entertainment system so that passengers could not figure out from the map that they were flying in the wrong direction, said a telecommunications expert who insisted on anonymity because he was not authorized to talk to the news media.
If the entertainment system was turned off, the satellite phones also would not work, the expert said.
