23/05 for sure, one study says a runway South of the terminal, another says to the north, so whatever is the cheapest I guess?
Another shows that the taxiway has been constructed as an 'emergency' runway to be used during the construction works?
Ask the local 'rather' activists dead set against runway 2.
Do a search on the WWW for the local campaigners, for sure they will have diagrams and plans that the BAA have submitted for a second runway.
