I was at the Blackbird Air Park when suddenly this black project hybrid airship took off. It has been secretly built by Skunkworks as a heavy-load carrier. To gain more span to act like a wing, the P-791 is three pressurized lobes joined together. It uses four air cushions as landing gear, located on the outer lobes. It appears to have four propellers-two at the tail and two on the sides. A hybrid airship derives most of its lift by lighter-than-air gas, the rest by its shape and span.
