no offence taken...
I think you're absolutely right about an increase in air rage... there was an incident on a flight I was on last week (SFO to LHR). 11 hours drinking, little sleep, cramped conditions... and then throw somebody talking loudly on their mobile phone into the equation and it's a recipe for trouble.
On the technical side, is the distinctive sound of the EM interference an annoyance or could it pose a risk?
