I have had a few thoughts about this and tried to simplify my objections.
This airspace grab really is quite huge and at low level involves grabbing a chunk of current Class G airspace and turning it in to Class D. TAG are claiming that this is for noise, ecological and Flight Safety reasons. They omit to mention that last June the MD of TAG Farnborough stated in an interview in Flight Magazine that having more control over the airspace would expedite the arrivals and departures for his clients.
It would appear that it OK for a light GA aircraft to waste time and fuel, but it is not OK for TAG's clients' fast, shiny bizjets to do so.
