Oh Leadsled spare me. You
do write brainwashed nonsense. Dick was THE architect of Airspace 2000, which was swallowed by the gummint of the time, and HE co-wrote NAS with Walter Dollman, I believe. That was in turn swallowed by the gummint of the day.
In short --- ICAO airspace classification, with the US NAS being the prime example, as ICAO classification is based on US NAS anyway.
Love it!
So once and for all (or have I already asked you?) why do you think that hundreds of thousands of fare-paying pax should be subjected to the unalerted See and Avoid threat of middle-level, unsurveilled E airspace?
