It was good to see Egon Musk's Falcon 9 rocket return to Earth the other day by landing the right way up on a floating platform. The video of it is here, along with a few clips of instances where this didn't quite go as well, and a nice explanation of the issues involved. It's good to see this reduction in waste. The manoeuvre reminded me of the comics I used to read as a boy when rockets always did this. Nice to know that real technology has finally caught up with tech-fi.
