'In an ideal World I would like to see one carefully located airport that would replace Newquay, Exeter, Plymouth and even Bristol with proper ground connections enhancing existing and adding new rail lines and roads in the area.'
Yeovilton, Merryfield or Dunkeswell, anyone?
Weston Zoyland would be better located than any of those, close to the M5 but with plenty of room for expansion. Still in use for microlights....
But I guess it's under water at the moment...
