Flying Fish
Air–Water Hybrid Vehicle Concepts
Over warm oceans, sailors have watched flying fish burst from the waves, spread wing-like fins and glide for tens of metres before dropping back into the sea. Some touch the surface, beat their tails rapidly against the water to accelerate, and take off again, extending their flight. They fly to escape predators below — dolphins, tuna, dorado — and they do it by crossing the boundary between two media that differ in density by a factor of about 800.
