I don't Believe it!!
This may be the silly season but this new proposal for an off shore airport must be a joke. If the powers to be thought Manston was just a bit too far away from London then why on earth are they considering this proposal. See http://www.bbc.co.uk/news/uk-england-20783474
Any off shore airport is problematic to say the least. We cannot even build an art gallery in the sea close to land (Turner Contemporary).
If the lunatics decided to build this it would require major road and bridge links in a hostile environment. It would need to be built several metres above sea level to take into account climate change and rising sea levels.
Placing an object like this in the sea would also change tidal flows in indeterminable ways to present more problems for shipping and coastal erosion.
The effect on wildlife and marine life would be devastating particularly so close to a bird reserve and seal colony.
It would also be subject to strong cross winds and gales not to mention flooding.
I think this must be another non starter like the other two suggestions to build in the Thames Estuary.
