"Iv sat on the flightdeck while taxiing once and overheard that familiar mobile interference (which you hear if a mobile is receiving a signal next to a radio or Computer) come through the earpieces in the flightdeck. I imagine that in critical situations this could be highly dangerous!!!"
I'll lay you odds that the phone in question was about the person of someone on the flightdeck . . .
