It's worse, actually. There are motoless gliders that fly up to 545 mph, and then there are tiny jet planes that go up to 465 mph. You can jam the signal, but as soon as someone can put an autonomous vision system on them, it will become an extremely powerful weapon. You don't even need an explosive at these speeds, it can cut your target in half
Frau Farbissina: We have developed the perfect assasination weapon! A silent glider capable of Mach 0.7!
Scott Evil: Great, now we just need to get the Venezualan President to give a speech at Torrey Pines or the backside of some other world class dynamic soaring hill...
Yep - you won't get 500+mph out of that though. And the 500+mph dynamic soaring "gliders" are neither simple nor cheap.
(That's only relevant to this sub-thread's discussion, your point is completely valid in the context of the top level thread... Having said that - needing balloons or planes to get your home-brew autonomous weapons above your target is a whole extra level of logistics and opportunities to get observed/caught compared to launching consumer-grade drones.)
