Didn't the govt. prattle on about "no new rwys in the south east"?
Yes they did, but if you float an island airport somewhere off the coast of Kent and it ends up half way towards Holland, then it is no longer in the southeast!
We need to ignore all those wonderful images of what Fantasy Island might look like, the only realistic one is an picture of white elephants in a formation spelling out three little letters: Y M Q.
I'd say 6 letters - YMQ-on-C.
Maybe with a few sticks of rock to represent all the piles that would have to be driven into the estuary just to create the foundations for this fantasy.
