When we saw this shot we thought it must be CGI. The thing is, how do you get a high quality camera 500 m above a rocket launch pad, and keep it there throughout the launch. This is the sort of thing you’d normally have to do, painstakingly, with animation and compositing
But this is real. We don’t have any real details except that this is was taken by a Hexacopter at the recent launch of the SpaceX Grashopper spacecraft, which is designed to take off and land at exactly the same spot – something of a remarkable achievement in itself.
