Now suppose you are a terrorist cell intent upon bringing down a few dozen U.S.-flag airliners (as in the Manila plot) and you know that broadband RF noise of sufficient power could do it. Remember - these people are fanatical, not stupid.
Could you disguise your device as a laptop or GameBoy and walk right onto a plane with it? Or build a timer into it and secrete it in a checked bag or cargo shipment?
Very highly unlikely.
And yes, I am an expert in those matters. Really.
