There have been far more accidents due to pilot error than there have been remarkable saves due to the human input.
Really? Care to back that up with some statistics? Of course you can't because the vast majority of events where the pilots intervene become non events
because the pilot's intervened and thus are not reported outside of MORs and company reports and are not picked up by the media.
The flightcrew are the last line of defence, the goal keepers in the system. The system stretches all the way back from the regulators to designers to manufacturers to operators to maintainers. None of those elements with all their potential human failings change by deleting the pilot. Yes you remove one potential source of error , but you also remove the last line of defence.
When a football team lets a goal in almost every case it is not just the goalkeeper who has "failed" - it's the same in aviation.
