A concept for an island shuttle. Ekranoplans fly close to the surface, taking advantage of the Wing In Ground effect (WIG). This makes them very efficient and fast. Isn't Jamaican Airlines' livery hideous?
The concept on this one is an absolutely MASSIVE flying boat with twin pontoons, and a wing so thick you can put a huge passenger lounge in it.
Here's a couple of views in the lounge, with Eileen Gray furniture, which would have been über-trendy for the time. Given the nationalism of the Twenties, they likley would have furnished it with Carlo Bugatti's stuff, but that was hideous, so we'll pretend they broke the mold.
