SOME DATA
Apologies for inserting facts and real data this early into one of Dick's rants.
This was provided by MITRE/CAASD to me when I was managing and regulating Australian airspace in the AERU in 2004. The dark blue areas are SSR coverage below 1000ft AGL.
If you want an interesting comparison, overlay the 2004 US Class D over the low level radar coverage. Ever wonder about the 700ft cutoff in most of it?
