Do you switch-off your mobile in flight??????

I received this article through e-mail and logically speaking there could be a high chance that our Cell Phone signals(Ignorant Cell Phone user) could be the culprit here. If you happen to fly (It doesn't matter whether Domestic or International Flight) please ensure that you have your mobile switched off or at-least in Flight Mode. 

Please do insist all your friends & relatives to do the same and create awareness. Often we assume that in the modern technology world, there is always a way to handle this automatically. But the truth is we do not have any system in place to handle this automatically at the moment. Cell phones and other devices that send or receive signals is generally (strictly) prohibited due to the potential impact on aircraft avionics and the potential for interference with ground cell networks.
