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.
Something I came up with as an alternate history for Russia in WWII - a rocket interceptor with tungsten steel spikes on all leading edges so they could ram their way through formations of German bombers. They were to be rail launched, and would deploy a parachute to land, after the rocket motors were spent.
Here's the emblem for a squadron of the interceptors. I think he looks a lot like William F. Buckley
Here's a cockpit view of some of the interceptors racing toward the bombers. What's not pictured here is the high-tech (for its time) vodka delivery system for the pilots.
I started playing with Photoshop's brushes and effects, and what better subject matter is there than Cthulhu? I have tons of these. My favorite is this grayscale one, everyone else seems to like the green guy with the dramatic blue background.
