Actually depending on the circumstances a computer pilot could be much more effective than a human pilot, then again when the computer is wrong the human pilot should have the ability to intervene.
I believe on some of the newest planes specifically the Airbus if I remember correctly if the computer thinks the human is wrong it will not allow the human to intervene this has led to preventable crashes because the pilot was not able to intervene and the computer was malfunctioning.
Sorry for the lack of details just a vague memory from watching old air crash investigations, could be wrong.
Thank you for this reply! I agree. Give me a computer that will override a pilot who decides to become a terrorist and crash a plane full of people into a mountain or other immovable object. Anything that a person can logically think through and is repeatable can be programmed into a computer as I'm sure you already know. I just hope they keep a person in the cockpit in some capacity.
