Private Jet-l agree with you on the Alconbury scenario.
Alconbury approach lights flash past the windows of the Eastcoast northbound trains exactly 35 minutes after leaving Kings Cross station.
But those who bought houses nearby will doubtless protest if such a solution is proposed......
Howzabout LHRs dep runway built as an image of Frankfurt, sod the M25, the longest circular car park in the world?
And the 4th "feeder" runway could be Northolt, rapid driverless trains to shift connecting SLF and baggage to/from the main site. But that would upset the too many, too senior RAF orifices who bleed the defence budget the same way as the more admirals than ships we have whose personal fiefdom would have to be shared with travelling peasants.....
Tin hat is on, awaiting incoming.........
