Petition Airport development fee should be charged on all users of London Airports to build an airport on artificial island in the Thames estuary without delay

It is irresponsible to cancel construction of a third runway at Heathrow, when it is already very congested & inevitable that soon will not be fit for purpose. A hub airport is analogous to a large central rail/ bus station, with huge enormous opportunities & facilities for connection/transfer onto other hubs or regional stations or airports. A major London airport should be always a hub airport as befits a major capital city of the world. Airports on artificial islands would reduce noise & smog pollution, congestion & acting as a barrier against flooding. There is already a design for a £20bn four-runway airport (twice the capacity of Heathrow) in the Thames estuary. Another £30bn to build an integrated transport links, a new tidal wave power generating station & a four-track high speed rail route system that circle London, linking the airport. This will be money well spent on acquiring real estate & infrastructure for UK, stimulating industry, economic activities, employment, etc.
