SpaceX Starship exploded in a fiery blaze during a routine engine test near Boca, Chica, Texas, about 180 miles from Corpus Christi. What happened?

SpaceX is still looking into what happened on Flight 9, an investigation overseen by the U.S. Federal Aviation Administration. So there was not yet an official target launch date for Starship Flight 10 — and, if there had been, it would now have to be revised after the events of Wednesday night.
