London gets floating airport?

It looks like a futuristic spaceship - but this is one of the plans being considered for London's new airport.

Designed by Gensler architects, the London Britannia Airport includes four floating runways tethered to the sea bed.

Extra runways could be attached as the airport expanded in future generations. Wind change? No problem – this airport is floating so you can just move the runway and anchor it somewhere else.

Being positioned in the middle of the water in the Thames Estuary would also reduce the amount of noise complaints.

The airport would be connected to London by high-speed rail. Passengers would arrive at the floating airport then be transferred to check in terminals on land.

If Gensler is successful in their bid to build the new airport it could be bye bye Heathrow.

The old controversial airport would be closed and transformed into an “eco-city and the largest urban expansion project in Europe” housing around 300,000 people.
