On this level, once you shoot out one rocket, you have to float as fast as you can to try to be in place for the next rocket (because the floating is so hard to control). There's no time to kill the astronauts; yet if you take time to aim, the laser kills you. Have been on this level for a year, and played it hundreds of times. Can't complete, it is even possible? In the time it takes to aim, the health goes from green to yellow to red. The furthest I've ever got is 4 rockets couplings melted. Has anyone ever completed this; if so, HOW??
