Good afternoon, I know this has been covered but I just wanted to clarify something specific.. I was in contact with my local class delta airport 10 miles out inbound to land. Overlying the airport is a class Charlie airspace that starts at 1200 feet. I believe I ascended into that airspace for about a minute before realizing and immediately descending. I went up about 70 feet (1270MsL) into the airspace. During this I was in contact with the underlying class D airport who said nothing about it. My question is: since I busted the Charlie, would the tower of that class Charlie airport get in contact with my class d tower to give me a number? If not, how would he give me that number? I didn't receive anything, but when I went home I filed an ASRS form to be safe. Do you think I have something to worry about? Thank you for your time!
