Well I guess there are many areas that they could cut redundancy. Why not scrap the second engine on twins? After all, today's engines don't fail, right?
How could anybody be stupid enough to suggest getting rid of the 2 cockpit crew? Airliners are always operated with the basis of having backups. When you get rid of the second pilot you loose half of your brain power. Hoe many little mistakes are made here and there that are caught by a second set of eyes.
This stupid idea will exponentially increase every type of accident out there. Plugging in performance numbers for takeoff? Maintaing situational awareness in mountainous terrain? Finding your way around increasingly complex airports without inadvertently crossing an active runway? Forget to set the flaps for TO? A lot of these mistakes have shown that technology has its limitations, as well as humans.
I hope the flying public is willing to accept a dramatic rise in aircraft accidents. I certainly will not get my ass on a airliner with only one pilot.
