Rocket Scares Cows

This is a very cool video.  It's a Space X  'Grasshopper'  rocket lifting off from a rural test pad, going up a couple hundred feet, then reversing itself and riding its thrust back to the launch pad. I remember seeing pretend stuff like this in space movies that predate the Star Trek era, but I never thought this kind of thing could actually work.  The proof is in this video.  Obviously, it was unnerving for a herd of cows grazing in a pasture adjacent to the rocket test pad.
