The point I am making is that an expanded airport is a not a sure fire winner to increase wealth in a city. Manchester airport wasn't that great an asset to the city. Many used the airport, but few went into the city - and the problems of aircraft pollution. That is not such a great problem at Liverpool as the planes come in over the estuary. An airport does promote business connections - eventually.
I would get rid of the isolated Speke housing estate. It needs lots of money spending on it which, with the poor image of the estate, may prove to be a waste of money in the end. The land is best used for airport expansion.
