There's a real asymmetry to the cost and complication of the problem and the solution.
I can buy, online, the parts to build a drone for a few hundred quid. A drone I could preprogram to launch, fly north 1000m, loiter for five minutes, fly west 1000m and ditch in the lake/river/woods/other place nobody will find it. No remote control needed, no GPS needed. Nothing to jam. If the loiter location was over the main runway at ($airport), how long would that put the airport out of action? Or, put another way, how many times would I have to drive by in a pickup and repeat this action with next to no chance of being spotted to bring the airport to a standstill at ($holidaytime)? Hypothetically?
Realistically the only way to combat this is some kind of directional EMP, if such a thing exists. And in any case, against any kind of organised group or even single person doing this you'd be playing wack-a-drone potentially for weeks. The only other thing you could do is some kind of blanket CCTV surveillance of the surrounding areas, but how far out do you go? Drones can fly FAST, which means they can fly far. The perp could launch from a moving vehicle conceivably MILES out from the target loiter point, and the drone could leave said vehicle extremely fast, making your window of opportunity to connect the one with the other a matter of a couple of seconds, if that.
To be honest, I'm amazed nobody has done it already.
