Thanks for the link! I was aware there were thrusters on top of the stage (otherwise the difficulty would seem impossible), but that description and the longer video were a lot better than what I'd seen previously. I couldn't dig up any specs on the cold-gas thrusters' actual output. I mean, how much tilt can they recover from on landing? Best I could find was this Musk response. "Q. In addition, can you talk more about the grid fins that will be flying tomorrow? How do they compare to maneuvering with cold-gas thrusters? The grid fins are super important for landing with precision. The aerodynamic forces are way too strong for the nitrogen thrusters. In particular, achieving pitch trim is hopeless. Our atmosphere is like molasses at Mach 4!"
