Re:Gatwick drones: Two arrested over flight disruption

I wonder if it is possible to disable a drone with a barrage of powerful air vortices. This would solve the GPS/camera navigation problem without disabling aircraft systems, and it would prevent any collateral damage caused by launching projectiles in the air.

It would need to be vehicle mounted and automated to fire rapidly, but would be interesting to see in action. (And probably a lot of fun to operate)
- the drones were flying high. Show me any sharpshooter that can shot down a highly agile and impredictible target at 200m high. Clay pigeons are shot at 60m on a very predictable trajectory, and even that requires a lot of skill and training.
- drones flying on preprogrammed path are impossible to intercept electronically, with the exception of GPS spoofing. Even that is difficult, never mind deploying GPS spoofers around the airport
- it would make the airplane operations impossible, so can't fly while the GPS spoofers are running, and when they're not running, there is drone flying
- the complexity of keeping drones in the air for long times (replacing batteries, field repairs, having spare parts) is not to be underestimated. This suggests a planned operation
