Rivet Joint, You are talking far too much sense for this thread and most of your comments are spot on.
Those against LHR constantly contradict themselves and I have not yet heard a viable reason no to build it.
We are told nobody wants to travel via a hub from a regional, then they talk about how many people are doing just that via AMS
We are told it's about demolishing houses or the poor people below the flightpath. Then they say expand Gatwick.
Then they fall back on the surface access costs borne by the taxpayer and complain about the north/south divide. The solution to this apparently is to build an island in the Thames and all the access to/from that which would be eye wateringley expensive, and, it's in the south.
If we are to build a hub then only LHR makes sense.
