The Avengers pack some pretty serious gear, and to haul that gear around, fictional government agency S.H.I.E.L.D uses the helicarrier (part aircraft-carrier, part-helicopter) to move it from place to place, undetected. It was only a matter of time before someone built it themselves, though.
This project sees Russian prop enthusiast Native118 rebuild the helicarrier out of a modified quadrotor design.
We see the carrier start at the waterline before firing up its engines. The water around it begins to ripple and the model helicarrier lifts from the water's surface like a hovercraft might. Impressive, sure, but the best part comes when Native118 ramps up the rotor speed and lifts the helicarrier right off the waterline and into the air.
I've watched this video about five times now. It's some seriously impressive stuff. Now shut up, and take my money. [io9]
