I remember once coming back from Florida over Charlotte, SC in a
friend's PA-24-250. We'd been slow-baking at 10,500 for about 3 hours
without O2, so we were probably both a bit hypoxic. We were going to go
right over the top (top is at 10.5)... they "refused," saying we could go
to
12500 if we wanted. Unable, so we were vectored 20 miles out of our way.
No I know the "correct" way to hand this would be to terminate radar
services.


The top of Charlotte approach control airspace is 10,500 MSL? That's odd,
these things tend to be at IFR altitudes. In that situation 11,000 over
Charlotte approach airspace would be virtually unusable.
