Spend out of the recession
Would a major project, such as the "east london" airport, be a worthwhile project, to provide work for many many unemployed workers.
At the same time, relocation of many environmently sensitive factory developments.
A new HI HI speed train system, linking the major urban areas, thus providing a more friendly heavy good transportation system.
The land that LHR occupies is prime residental land for London, and as such would have a positive cash flow to this project.
Perhaps also relocate LGW as well, with a HI HI speed rail, looping from Brighton via the Gatwick area.....
Unless GB PLC acts soon, all the profitable by product of the major hub UK has provided till now will be lost FOR EVER.....
Relocate the capital there too........ Cambera (east).....
Build the New Thames Barrier, let the land side silt up, have a cosmetic River Thames, and gain all the usable land.
