By the way, Skipness, the Liverpool - Manchester - Leeds (- Sheffield / Bradford) - York - Newcastle rail corridor is also a national asset in the same way LHR is. Although I do realise that you're probably choking on your lunch contemplating that concept.
No just wondering how mixing apples and pears furthers your argument. One brings in much needed international investment from across the world, our clients deal much more with one than er.....Leeds Railway station. I think when you say "the same way", you're stretching things to breaking point.
This response is based on faith. None of us knows the future, especially financial forecasts 60 years out. What we do know is that LHR R3 is extraordinarily expensive to deliver here and now
Like the Channel Tunnel. Don't build that? The London Olympics? Don't hold them? The Edinburgh Trams? Actually, that last one, beyond barmy(!)
