Greetings,

PEDs are not to be used during takeoff and landing, indeed, the industry considers that although most of them are very well isolated when new, they will lose this isolation with time, and start leaking electro-magnetic...:ok:

"Not sure if Boeing have tested the use of mobile phones in flight, I suspect they have and would be the best people to ask since they build and test them!"

Well they certainly worked on board the airliners hijacked on Sept 11th 2001.

Or did they?
