I’m still trying to understand the details. I hope that this data is correct, please confirm o correct them:<p>This video was filmed yesterday (2014/04/17), it’s a launch of the new v1.1 model (<a href="http://en.wikipedia.org/wiki/Grasshopper_(rocket)#Grasshopper_v1.1_2" rel="nofollow">http://en.wikipedia.org/wiki/Grasshopper_(rocket)#Grasshoppe...</a> )<p>This is not a video of the launch of the old v1.0 model (2013/04/17 or 2013/08/13) that also reached 250m. (In another test, the old model reached 744m before landing.)<p>This is (obviously) no a video of today launch to send cargo to the ISS (uses v1.1 model)
