Flying straight and level is More or less the me dificulty of driving a pedal cart in your street (with an added dimension up and down). Old time jets were very tricky to flight due to their high inestability. But modern flybywire combat jets must be easy to fly( even if they are impossible to fly without computers due to their crazy inestability), because the hard part is outside in the combat theater.
Also like in sea combat, the most important part is not being a skill beast (aerobatic champion), is more about knowing how to obtain the best positions, that gives you advantage against your enemies.
Any way I don't see rat brains landing in a n aircraft carrier anytime soon!
