If a Pilot needs to be tapped on the shoulder by a passenger, the Pilot shouldt be flying.
I wonder, would a Pilot Observer have been of value? Is it worth the loss of $150 a flight to be safer?
You are somewhat contradicting yourself there - on the one hand you suggest that the pilot should be all seeing and all knowing, without any external assistance, on the other hand you suggest that maybe he isn't all seeing and all knowing, and could do with some assistance!
