 uh... in almost every way every one of the flight to engineering test so if there was an explosion or didn't quite go it's supposed to that was not a failure that was just simply them try to figure out what's what to build or what not to build about by the fourth flight that happened in june uh... not only did the first stage called super heavy uh... do its job perfectly but it then controlled and brought itself down vertically at the exact spot it was supposed to be in the gulf of mexico
