Mr. Ziemba is an "Alarmist" when he talks about "Drone Aircraft" and has distorted the facts. I've read both of his articles and it sounds like he is trying to protect his turf as a pilot.
In a sense, we already have thousands of "Drones" flying over America every day in Commercial, Private and Military airplanes. Modern aircraft charts are only sheets of paper with lines and dots with radio frequencies. Pilots pre-chart their flights into a computer and once the plane is airborne they flip a switch and sit back while the airplane flies itself, climbing to altitude, leveling off and flying from dot to dot on the chart until it gets to it's destination and then the pilot takes over to land the airplane. (Most aircraft accidents happen when landing and taxiing while pilots are in control.)
When you read about an airplane crash, there is the pilot and usually innocent people on board who die because the "Pilot" made a mistake. In the future there will be no need for pilots except to make passengers "Feel Safe" and that is why Mr. Ziemba is against the idea of Drone aircraft.
It is true that there are many crashes of drones in the War zones, however they are flying in hazardous and unsafe conditions. These drone aircraft are designed for military operations, not Civilian, and vary in size from small, hand launched model airplanes to medium transport sizes and are expendable. They are designed to do specific missions and are accomplishing them.
Civilian "Drones" are coming and will be safe, however I feel that it will be another ten years before passengers will be flying in aircraft without a pilot on board.
