In 1981/2, the CAA and NATS (not Farnborough) wanted to put controlled airspace over Lasham with a base of 3,500ft.
Lasham objected and so for years, Southampton arrivals were forced to fly through small portions of what we now call Class G airspace until the Southampton CTAs could be re-designed.
Lasham and the BGA have always moaned and bitched about controlled airspace around them and any compromise suggested has been met with replies like 'well can we have (this bit) as well' or 'couldn't you move that boundary back by a couple of miles as it prevents us from tracking direct to various competition turning points'.
Whatever you do, whatever concessions you make, Lasham will always want more.
