Just one final note. There is only one type of "commercial" pilot in the United States, that is one that has an instrument rating. If you don't have an instrument rating they only allow you to fly 25 miles from your departure airport (scenic flights). I wonder why that is? Maybe, the Americans realise that you can't fly around in ignorant bliss and call yourself a professional either!
Unbelieveable, so nearly all flights of a distance greater than 25m are under IFR rules, well that changes things a hell of a lot in comparison to Australia, because most flights would be known if they are in class E, as they would be IFR, but this is NOT THE CASE in Aus????
Dick I believe you CERTAINLY DON'T have a full understanding of the US System!!!
