Do u honnestly think experience only makes a good pilot ?
Then u must be reading a lot about safety u claim to worry about ... How many aircraft crashed after experienced captains made the fatal mistake ?
Human errors is behind most accidents regardless of experience. Airlines should pay attention to the personnality and the reliability of a person not necessarily its experience. Don't get me wrong, experience is necessary but it doesn't make u safer ... I'd rather work with a low houred FO who's doing what he's supposed to do (being a pilot) than with a 4000 houred FO thinking he knows it all.
Professionalism my friend
