This bug happened to me today. Flew a shuttle to space and closed the game. Next day I launched a rocket to refuel shuttle and flew the shuttle to a space station around Mun. Came back to Kerbin and was perfectly lined up to land at KSC coming from the West. I used 4x physics warp during the descent and when I came out at around 10km away a delta wing exploded (flight log said crashed in launch pad). At first I thought the cause was the physics warp. I managed to keep the shuttle steady until about 3 km out when the other delta wings and B type wings IIRC, all exploded. They all "collided" with the launch pad. I will post pictures if my shuttle tomorrow. I use the following mods: FAR KW Rocketry B9 aerospace Kerbal attachement system Navyfish docking cam Kerbal alarm clock Flight Manager for Reusable Stages
