Hang on a minute!! Railways have always been a form of public transport and have never had significant private traffic and they have to have the infrastrucutre before they expand. The same rule should apply to airports and airspace. Why not cap capacity pending improvements in airspace at a sensible level i.e. "if you 've only got two tracks you can only run two trains" for now. Trouble with London TMA airports seems to be they are limited by runway slots but no take no account of airspace - how about an airspace mediated slot policy or a combined approach. Then Manston could really fly!
Anyway did any business jets (rich private not like me with my 180 horse Lycoming or the para droppers) contribute? If so they surely should be at the back of the queue
Just trying to stir really
Accept though that those of you trying to do a honest days work are caught up in the middle!
