If in doubt, there is no doubt surely?
The case for saying 'it's not happened yet' is frankly ludicrous. I thought the aviation business worked along the lines of prevention as opposed to cure. The cure is usually the result of something going very wrong.
Do you really need to use your phone that badly? I thought thats what answer phones and text messaging was for?
Because of the vast array of different avionic systems out there, you can be sure that one of them will get affected by a rogue signal. It just aint worth the risk. Certainly not taking the 'well its never caused a crash before' stance. I'd rather not be the one to make the precedence that proves the point.
