I'm indebted to Russ Niles of Avweb for an extraordinary article headed 'Radio Gun Disables Drones'
http://www.avweb.com/eletter/archive...t=email#225013
It starts
A non-profit corporation with a long history of developing new technology ... has come up with a way to harmlessly disable drones that are flying where they aren't supposed to be flying.
The corporation is Battelle - I'm ashamed to say I'd never heard of them. But the article is illustrated with a promotional vid. When I'd watched it, I had to check to make sure the date wasn't 1 April. It looks too good to be true, and we know what that means...
But no, it seems kosher. Amazing.
