What made me chuckle about the original article was the notion that a co-pilot might crash an aircraft by being a bit fatigued! Surely when things start going slightly awry, due to co-pilot fatigue/nerves/inexperience/ineptitude, the captain steps in?
Anyone ever heard of a co-pilot managing to bring death/disaster/crashes by being slightly tired?
Or was that quotation just part of the unauthorised amendment?
