Video: NASA’s Greased Lightning GL-10 is a beast of a drone (it has 10 engines!) that’s the closest thing we have to a Transformer in real life. It can flip itself into a helicopter and then fly like an aeroplane and then revert back to helicopter mode. It’s awesome seeing the wings tilt back and forth as it changes gears.
