To be fair, if you look at the video, you will see that they landed on the moving barge just fine. It was standing still on the platform, stable, with engine disabled.<p>Of the locks keeping the landing gear in place, 3 out of 4 succeeded. Whoops. Maybe they should simply switch to 5 or 6 landing gears. After all, they went for 9 engines and can boast multiple launches where one or two engines failed (including this latest one. One of the engines shit itself while the rocket was returning to the barge according to the twitter feed).
