Makes sense. You already have the platform. You just need to develop an RC interface to the autopilot.
Most any sharp college grad with mechatronics experience could do it, so no surprise. Our US universities with engineering departments enroll significant numbers from the (well funded) middle east.
I would expect the Israelis to be able to down anything suspicious that approached their airspace, so that could mean that perhaps that a swarm of drones could take off on short notice, fly towards Israel, then let loose chem-warhead-armed air-to-ground missiles right before the drones would be expected to be shot down by the Israelis. The missiles could penetrate further into Israel to strike preset military targets or population centers.
The mission could even be designed to be partly flown with human pilots who could handle the take-off and then could eject right before crossing the Golan or into Jorday. The drone Mig-21s (obsolete planes) could continue into the “suicide zone” of protected Israeli airspace.
I think the tally was 95-0 during the last tangle between the Syrian and Israeli air forces, so using pilotless planes on WMD missions would mean that Kamikaze one-way missions wouldn’t be needed that would kill valuable (secular non-Islamist) Syrian pilots. Talk about inviting further defections!
