First off, no, it’s not that song by Grease. Second off, who ever thought greasing lightning was ever a good idea? Apparently NASA did, when they created a 10-foot wide, 62-lb, 10-engine drone, capable of vertical liftoff like a helicopter, and regular flight like an airplane.
As they continue to scale up the tests and the model drone sizes, NASA hopes to be able to someday convert this tech into a 1-4 person-size personal air vehicle. Greased Lightning, or GL-10 is a quiet flier, as its engines are battery powered, with NASA describing it as quieter than a neighbor using a gas-powered lawnmower in the adjacent yard.
NASA is currently looking at reconnaissance and agricultural uses for the drone.
