So you see here, I designed a mission for Jool, and sent it to land on all planets with dragons. However the dragon dispatched to laythe didn't have enough fuel, and it was coming in hot- the engines failed and it hit at a whopping THIRTY METERS PER SECOND, the RTG and decoupler exploded... but then... It survived! (NOTE: The MJ landing is only there in case of emergency attempt, but I did not use ANY MECHJEB on this mission). There is only one weird thing: It's sinking. I managed to slam into the water so fast, somehow it doesn't float anymore! And now they wait... Has anybody else survived a rough landing or managed to create a submarine accedently? Currently -130 meters and sinking....
