Another positive
I know that quite a few people gripe about airspace usage. Compared to the rest of the world and especially Europe, we have it made here in the U.S.
Europe uses an ICAO-style airspace system. Some of the things that pilots there must endure we wouldn't stand. E.g., filing flight plans for EVERY flight (well, maybe that's not that bad an idea). PPRs (prior permission required) to takeoff and land. Low transition levels, meaning some sort of postive control is REQUIRED at altitudes as low as 5000' MSL. I believe that European pilots have to pay takeoff and landing fees every time they. Finally, fuel is much more expensive there than here.
Bottom line: Flying may be expensive here, and it is; I know, and, seemingly, restricted, too, but not nearly so as it elsewhere.
