Why not double the size of EMA. Add thee runways.
It has HS2 beneath it. They could build a dedicated station.
Short distance by tgst train to central London.
Move a. The freight ops to DSA which is about to be connected to a major rail freight hub and massive business park and cargo facility.
Even build a station at DSA linked to the ECML.
And perhaps persuade some EU carriers Eg Lufthansa and German wings . For example to shift spme uk destined flights there.
Not every flight neefs to Land at LHR.
But EMA is Right off the M1 and close to MR M62.
Has an already large catchment.
With the frieght ops moved to Dsa which is geared toward major freight ops has we hour ops.
It would free up the old Cargo terminals at EMA to become new state of the art passenger terminals.
It has a dedicated station now.
So why can't we make it the UK hub.
Encompassing Scotland and Wales its central for the whole UK.
With all cargo relocated to DSA. and it's not vastly bust slots and airspace are not an issue.
Granted Ryanair would need to move out. But again they can go to DSA.
Any holiday routes can do the same Eg Thomson .
Monarch have left already.
DSA can support more movements and I see cargo being a big thing.
EMA is perfectly placed as a hub.
Thers open fields galore to build all the runways and taxiway you'd ever need.
Ok the M1 woukd need widening again to D5 which would mean widening toward Kegworth.
Might be tricky v but achive able.
Perhaps a new Airport junction and Motorway spur From.the M1 would help.
And it keeps this London centric old boys network of everything must go.through London or the world will end quiet because in the end they would see it makes sense.
Close LHR and regenerate that area.
But vastly improve the line upto Nottingham and push through HS2 extension asap.
There's too much dithering.
London airspace is so crowded .
What with noise and pollution.
Plus All the Surrounding London airports including LCY there has to be a point where there can be no more airspace capacity.
