Here's some more facts:
Original planning app made in the 1990s
Renewed at least twice.
You'll find that permission was granted for a terminal (Just siting) in 1998 and lapsed in 2003. The airport (Owned by those Atlantique/Atlantic people or whatever they were called) submitted a new application that was refused... And then the whole saga started with the IPF & TUI eventually bought the airport and submitted a new planning app in 2004...
The original renderings of the plans used to be knocking around on the web somewhere. You might still be able to find them.
