Re: What about zapping it with high powered radar?
"How about a short burst of a high powered radar to fry its electronics? just a short burst, when no aircraft are in the line of sight for the radar beam"
And this would work why?
1. If the radars don't do it now, they won't do it later. It's not like they are built to produce 100 times the needed power, and then forever run at 1% output.
2. Other than approach, landing, and ground control radars - all relatively short ranged, air traffic control radars are likely situated well away from airports, on high terrain that gives a good all round view to long distances.
