Festo Air_ray R/C Blimp
Sometimes it takes videos like thisto really drive home the fact that the atmosphere is really just a biggas ocean, that displays basically the same physical properties as aliquid ocean. Festo took this concept to heart when they designed theAir_ray, a remote controlled blimp that swims through the air just likea manta ray. Theblimp is filled with helium, making it buoyant, and contains servoswhich flap its wings, propelling it through the air and allowing it tomaneuver. It also seems to have a movable tail to control pitch.
