Why do the supporters of a bigger LHR not think that other parts of the Uk should not have good links too. London has a population of circa 10M about 1/6th of the Uk population so it should not call all the shots.
We don't, at least this one doesn't.
Expansion should be allowed
wherever a business case can be made.
Under the UK system it has to be a business case because most airports (certainly the major ones) are privately owned and the govt also doesn't have any spare dosh.
Realistically expansion away from LHR on it's own isn't going to solve the "LHR problem".
BTW, it's not about the proportion of the UK's population, LHR is a global airport, the UK's only one, and one of just four in Europe.
I believe you are wrong A monorail journey of 10 miles would take 15min from NRT to T5 with no customs or immigration to consider It would be like LCY where you can be on a train within 10min of disembarking it would just be like a spoke of T5
It's
slightly more plausible than "Heathwick" because the distance is only 6 mi. and no international-international transfers would be involved, but it's still unfeasable.
There isn't going to be a monrail, the best you could achieve would be a dedicated bus link, but that would be proned to traffic congestion, road works, accidents, etc..
In the real world, you have to ask your self the following:
Is there a business case for at least a terminal and railway station at NHT (with a station and fast trains on Chiltern, NHT would be as convenient for London as LCY)?
Would any carriers be interested in NHT operations (it is in a very large and very rich catchment area)?
Would the military be happy with such arrangements (it could be a nice little earner)?
Would Boris try and have it shut down and 200,000 houses built (NHT is in his constituency)?
There could be potential for a small local airport at NHT, but as LHR's "domestic terminal", not a chance.
