LOL, what are you going to do? Sit at the end of Northrop field and fly a swarm of drones into the engines of a G6 traveling down the runway at over 100MPH? No way a handful of drones are going to get sucked into a jet engine at that speed. Or do you mean engage a PJ in a dogfight at 40000 feet? I suspect if drones could down a jet, we would have heard about it coming out of Ukraine by now.

The reason we don't do these things is because the jets would come crashing down onto someone's home or place of work. That UPS jet that crashed last year when the engine detached on takeoff killed a dozen on the ground. Nobody is going to drone attack a private jet because the innocent would get killed by the dozen.
