Hand Solo,. .How about one pilot fly's the aircraft and there are two guy's to go through the checklist and take care of the problem.. .A lot less stressfull than in a two men crew(even that modern a/c with "working"autopilots help a lot too).. .Believe me the F/E's technical knowledge is a LOT better than that of the Pilots (overall),and is well worth the beers you have to buy him in the hotel.
