RKT and NGL are both drone plays.
The NGL "Blackbird" drone in particular was custom designed by the co-founder, who happened to be one of the first engineers at SpaceX and who worked on the Falcon rocket navigation system. And he has a PhD from Stanford in rocket science. Literally a rocket scientist.
Additionally, at Willow Garage, John was responsible for defining the vision for the autonomous car project.
