The movie Grease ends with the car Greased Lightning magically flying off into the sky. This must have been bugging someone at NASA – the agency has named this weird aircraft after John Travolta's ride.

Publicly, though, it says the name refers to the drone's two-step propulsion system: diesel engines inside the fuselage that can run off fuel derived from fryer oil (grease) and which generate electricity (lightning) that powers 10 propellers.

The propellers festoon the wings and tail of the 3-metre-wingspan GL-10 Greased Lightning. For take-off and landing, the wings and tail point upwards and all 10 propellers spin to allow the drone to hover. Once airborne, however, the wings and tail pivot to horizontal and the two outer propellers on the wings drive the GL-10 forwards.
