(First post, yay!) My best fail thus far was also one of my first. I didn't quite have the concept of deltaV down yet, so my Munar Lander was a little understocked for fuel and ended up stranded after landing. I ended up having to send up a separate rescue craft - basically, the original lander with all the science instruments and living quarters replaced with fuel and a probe core for unmanned flying. Not quite knowing how to land accurately, I set her down on the wrong side of the crater, and had to EVA my crew across to board. Jeb and Bob made it okay, but Bill managed to run out of EVA fuel about a kilometer over the crater. In Pace Requiescat, Bill Kerman.
