Today at approximately 3:27 PM CST, an "anomaly" occurred with the SpaceX Starship MK1*, causing massive failure. This happened after a full pressure test on the evening of November 18, during another test this afternoon at SpaceX facilities near Boca Chica, South Texas. Thanks to the efforts of several intrepid live video documentarians, we can see the rapid depressurization and explosion frame-by-frame. NOTE: To be EXTRA CLEAR - this was a prototype unit undergoing pressure testing. Testing is done to avoid situations like these during actual live launches.
