The Judge is overstating the case. There are only 200 or so drones (actually MQ-1 Predators and MQ-9 Reapers) in the inventory. General Atomics is the manufacturer and each unit costs 5-9 million, depending on the airframe and sensor package. The supply line only provides 100 airframes per year, on a good year. So, the math tells us it will take 300 years to get to his magical 30K number.
MQ-1s and MQ-9s cannot fly over private property (and most public property) because the FAA will not allow routes over unrestricted airspace due to the fact that the airframes are unmanned.
I usually nod my head in agreement with The Judge on most of his columns, but this one is truly a whopper.
