I may have it wrong, but my understanding is in the U.S. Class G is
uncontrolled airspace, and Class A is everything from 18000ft to
60000ft. Well, the balloon will definitely go through Class A in this
case. As far as Class E and G, maybe I am reading the charts all
wrong.

Looking at the Skyvector site, lets say I were to launch at 36N 87W
near Nashville. If the wind were to push the balloon east or north it
could drift into Class E space briefly. Otherwise, the balloon would
only be in Class G then A. No?


At 36N 87W, starting at the surface and working up, the airspace is Class G
to 1200 AGL, Class E to FL 180, Class A to FL 600, and Class E to where
airspace becomes just space.
