Robotic Planes

Planes are becoming more and more electronically controlled. Already, pilots are only flying the aircraft  about 7 minutes manually operating their aircraft. Commercial and cargo planes are controlled by an autopilot that tracks the position of the plane using motion sensors that is corrected by a GPS. Manually controlling the plane is becoming less and less needed. As there are already over 11,000 drones used in the military, the military has already invested in automated aircraft. But these drones are remotely controlled by a human on the ground. What is being developed right now for commercial airlines is, as the first step, a robot that will act in place of the co-pilot, being able to speak, listen, and control the aircraft and take over the flight in case of an emergency.The recent Germanwings crash has raised the question if there should be some way to instrumentally control the aircraft from outside the plane, as a group controller. This would give the person controlling the place from the ground the ability to guide the plane if the pilot become incapacitated.
I agree and disagree with what is happening on this matter and what is trying to be accomplished. I don't believe that human pilots can be entirely substituted for robots, for a few reasons. First, a robot doesn't have human senses. They cannot physically see what's in front of them, they can't smell a possible problem on board the craft, and they can't register the emotions of others on the plane. Another reason I believe that a plane piloted automatically would not work is because people would simply not trust a robot to fly them 1000 miles to their destination, and safely land them. I sure wouldn't. I'm suspicious of planes already, because when I think of how well regular electronics work, like my printer or computer, I'm amazing how rarely there is a problem with aircraft. I believe they could eventually get the robot pilot right, but not after a few failures, which could cost the lives of thousands of humans. Where I agree with this article is the part where the plane can be remotely controlled by humans on the ground. This would reduce the risk if the pilot becomes incapacitated or goes insane. If the worst comes to worst, which doesn't happen often, there is still a cool head on the ground who can guide the plane down.
