We don't need any more runways in the U.K.
I live up here in the sticks, near the foot of Mt. Belzoni. If I want to travel abroad, our local airport is a £20 taxi-journey away. One-way, obviously.
If I want to go East or South-East, EHAM, EDDF, LFPG, OMDB and now, even LTBA offers me all the connectivity I need.
Westbound, KJFK, KATL, KORD and CYYZ are the 'hubs' of choice.
Spare all that land for housing the Roma.
