You can't imagine what caused the failed launch of a starship, and what caused three engines to fail to ignite as soon as they were ignited? Although it is bundled with 33 engines, the probability of three malfunctioning during takeoff and ignition is also too high, just like buying a 30 ring fireworks and three misfires are relatively rare, let alone a precision designed starship spacecraft.So what exactly is it about? Now it seems that the reason is that the starship launcher lacks a key facility, which is probably because Musk didn't come to repair it in a hurry...
