Elon Musk's unmanned SpaceX Starship experienced a failure today:
SpaceX’s engineers are still sorting through exactly what went wrong with the uncrewed vehicle. Mid-climb, a few of the 33 Raptor engines appeared to flame out. Within three minutes of liftoff, the Super Heavy booster was supposed to separate, but that never occurred. Instead Starship began to spin wildly, tumbling through the sky. Then, the vehicle exploded, which SpaceX later said was triggered on purpose with flight-termination commands sent to both the rocket and booster.
SpaceX expressed it this way:
“Starship experienced a rapid unscheduled disassembly before stage separation.”
Addendum: Explanation in one of the Comments. But it reminds me of this old skit:
