One thing you can be sure of with ATC. Only one controller owns the
airspace at any given time. Those two facilities have gotten together
to iron out the airspace.

Yeah, but look at the altitudes. The top of the Class D appears to be
_above_ the floor of the Class C that it overlaps.

The class C does not exist where the class D does.


Are you sure about that? Providence Class C protrudes into Quonset Point
class D airspace and the Quonset Tower is very adamant that the overlapping
area is Class C and requires communication with Providence.
