Silverstrata you may well be able to fly a plane but since when has that made you an expert on planning, civil engineering and architectural matters. Have you studied Lord Foster's proposals in detail. The newish Hong Kong airport designed by Foster has it's terminal at one end and works well. A terminal in the centre of the airport will as in Heathrow at some point restrict future expansion. As for your comments re settlement I guess you must have a beta version of the yet to be released Microsoft Civil engineering simulator, but what do I know am only a "brain dead Architect"
If you want a meaningful discussion on a new London Airport I suggest you would be wise not to alienate the very people who can contribute something to the debate.
