LO,
I get your point about auto-land but you cant always rely on it. Chances are that some part of it (ship/aircraft) will fail some of the time and you're back to manual. Again, chances are it will be blue water/no div in black as a witches t*t weather. Do you really want the guys/gals to not bother practicing manual landings???
Come on man are you really that naive as well?
