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. We have Class A,B,C,D,E and G Airspace. The Airspace overlays
the Airports. Now show me where in the Aeronautical Information Manual
(AIM) or an FAA Approved government publication that mentions a class
B,C,D Airport. You will not find it...

Take the time and choose your words carefully.
