It's funny, so many assumed in here that MOL was talking about UAVs and Avionics negating the need for first officers....
He was pretty clear that the first officer being an extension of the captain, who basicaly did everything, was his reason for feeling that FOs were pointless...
The sad silly fact, is that you don't need to have abinitio schools, or hire weak FOs, plenty of experienced pilots out there, plenty in the resume pile that want a shot at flying airliners....
As long as airlines continue to hire based on attitude, ability to conform...a pliable marshmellow that will fly with the captain into a mountain...guys like MOL will continue to ponder why your typical FO is even neccessary.
