Fairdealfrank you have eloquently put across some very valid arguments and points of note. The most notable of all being:
The facts are simple: Heathrow needs two more runways, and it needs them yesterday, there is no getting way from it, and it will happen, probably later rather than sooner regretably.
I couldn't agree more with this last comment. Heathrow is in dire need of two more runways, and it's about time the powers that be did what is required. I, too, fear it will be later than sooner, but one can only hope that the new runways at Heathrow and Stansted will be built in the near future.
