EMP PULSE RAY. EPR
A possibility. I had wondered in a previous post whether these aircraft were all fly-by-wire - that is, with no manual control. Because absent the ability to take matters out of the electronic's control and directly into the pilot's hands, any electronic failure could potentially crash the craft.
I don't really know much about the EMP technology. I know that it's touted, perhaps sensationalized even, to be able to essentially fry electronics and possibly larger electrical equipment. Worth studying.
In the middle of three deserts one of which a monitored range and another at night in the forests of Tennessee? Pretty mobile.
