Hi curiousgal,. .Just a thought...
I take it you were in the back using a scanner, not in the cockpit?. .Surprised the cabin crew didn't object if you were using a scanner. Current security climate aside, they're briefed to watch out for any electrical devices which could interfere with avionics. Admittedly a scanner by design shouldn't put out too much RF noise though.
If I've got hold of the wrong end of the stick, disregard all after "hi".
Cheers,
