CLAPTRAP
UNPROVABLE
ALARMIST
MEDIA GRABBING.
DONT FALL FOR IT.
Oh really.
I'm glad you're so positive about it, because I am equally sure that I really did see the outflow valves on the 747 classic I was on, on the ground, shut all by themselves. The FE ran back to the upper deck and found a passenger that was talking on a mobile and got him to turn it off. At the same time he did that, the outflow valves both opened up again.
This is a known occurance with 747 Classics.
I also have spoken with the ex-boss of Air Safety in Fiji who saw in person the needles on the VOR in his light plane go beserk when his passenger used a mobile on the plane. Again it stopped as soon as the phone was turned off.
There's a LOT more examples if you care to extract your head.
However, Boeing have made an effort to improve the internal protection from RF interference - They have tested the 777 when full of employees that were asked to carry everything electrical they could with them, and then use it.
There were no effects on that flight.
Mobiles + aeroplanes = bad, period.
