A few good points there Northbound, but Cobham tried to move elsewhere two years ago and they quickly realised it was unfeasible, and I think Cobham would easily take on Peel! The Wright Brothers may have invented aviation but Cobham more or less developed it thereafter!
I personally don't have anything to back this next statement up, other than I've heard it from multiple people, but apparently, if Peel do want the land, it's a damn sight more valuable with an airport on it, so providing they make moves to build up the airport as well, let them crack on a build whatever takes their fancy elsewhere on the site (I still think they're very limited with what they could build, if anything).
When this master plan gets released, Peel are going to have to try and pull something special out of the hat to bring in some very positive
PR.
