"Lets get to the bottom of this.
I constantly hear people refer to Airports as being class B,C or D
Airports. Any of you who have thorough knowledge and understanding of
Airports will know that there are only two kinds of Airports in all of
our National Airspace System (NAS). There is Towered and Non-Towered
Airports."

Are you the same guy who complained people used the term "automotive
engineer" incorrectly by referring to engineers who worked on cars?
His claim was that the term implies an engineer who works on any
self-propelled vehicle. Maybe an etymologist would agree, but when
"automobile" and "automotive" are pretty much universally understood to
mean cars and the like, the distinciton is useful.

And, by the way, it should be "There _are_ Towered and Non-Towered",
not "There is..."
