Disturb' With the safer FAA NAS system when a D tower closes the airspace becomes E and the Centre controllers provide the IFR separation service- very often in a non radar enviroment.
Now I know that this must seem an impossibility to you - with the E down to 700agl-simply cannot work!.
Imagine en -route ATC's who are also approach rated!
No- lets get more G so airline pilots become the ATC er- more profits and bonuses for AsA that way!
Forget the safety aspect.
