For at least the 50th time class E terminal airspace to 700 agl does not require VHF or Radar coverage in North America.
Every instrument approach is in a minimum of class E and it would not be possible considering the huge size of the USA and the many valleys and mountains to have coverage down to 700 agl at every one of these airports.
But after 24 years of repeating this myth I suppose it becomes as factual as Bigfoot.
Resist resist resist change in every way you can. Wait for the Royal Commission after lots more uneccessary deaths like Benalla
