You seem to feel that farm land has no value. Not many will agree with that,
least of all the peope who live near Stansted and who have made clear their
intense opposition to any expansion.

The rail line from Stansted to Liverpool Street is not Britain's leading rail route
and already has capacity problems in the London area. I doubt if more
international travellers want to be in the Liverpool Street area than in the
Paddington area so that argument has minimal validity.
