Blue side up
Well done , you got to the heart of the matter in one sentence.
we in the UK are so great at telling everyone else what to do but cannot do it ourselves. practising and preaching.!
The area north of LHR is extremely underpopulated compared with most of west London and includes agricultural land , gravel workings and alot of wasteland. Why , because just for once someone back in the 50s thought maybe one day they will need another runway. So the space is there already not all of it but a lot.
As for the build a runway at LGW or MAN they just cont get it do they . All big cities need an interchange airport where transit passengers are a significant proportion of users but tis not just about proving that service adding these to O&D pax and you can justify new routes. . Another runway at LGW just means more Easyjet and they only fly to Europe the land we hate and despise so much apparently. No one in their right mind is going to travel from LGW to LHR let alone Manchester and as for Boris island I think the whole country maybe even the whole world knows anything proposed by that idiot cannot possibly have any merit . How would all the immense number of business people who live in the LHR catchment area get to the Isle of Sheppy -high speed train maybe , by 2025 that will cost about the same a cheap Y ticket to JFK before you even get on the plane. And as for noise pollution-hello what do you think those shiny silver things flying over every day are doing
