SpaceX CEO Elon Musk took to X on Thursday night to explain what his company believes may have caused part of the Starship rocket to experience a "rapid unscheduled disassembly."

SpaceX launched Starship on Thursday for a seventh test flight, after weather concerns pushed back an experiment that will feature the spacecraft’s first payload deployment test, and while it successfully caught the Super Heavy Booster, Starship lost connection and “experienced a rapid unscheduled disassembly.”
