Bill Harris,
If you look at the Flight Track Log I embedded in an earlier post you'll note that the aircraft reached an altitude of 33000' which it flew at for 3 minutes.
My understanding of the Cessna 421 is that it has a service ceiling of 30,800'. If that's the case, this aircraft flew above its service ceiling for well over 30 minutes, reaching the aforementioned 33000' twice.
Again, being ignorant of these things I don't know if this is "normal" for a pilot to fly an aircraft above its service ceiling for over 30 minutes but it does strike me as unusual. Or am I off the mark here?
