Slightly off-topic. What will be the NEXT full-length runway in the UK?
IMHO, it will be Pembrey - since the motorsports centre that currently cuts its tarmac in half looks like going out of business. This would allow something called the Swansea Bay Airport to come into being, with 2,400m immediately available and 3,400m in a year or two. Such capacity would allow for a major MRO and training facility (including A380 revisible runway capacity), plus a rather small local domestic passenger operation.
Just check out Google Earth/Maps to understand this. And consider that less than £1m would produce a facility employing maybe 5-700 people? Right next to a mainline railway and just a few miles from the end of the M4.
A better proposition than Southend or Manston, probably.
