 in almost every way, every one of those flight to engineering tests. So if there was an explosion or it didn't quite go where it was supposed to, that was not a failure. That was just simply them trying to figure out what to build and what not to build. But by the fourth flight that happened in June, not only did the first stage called Super Heavy do its job perfectly, but it then controlled and brought itself down vertically at the exact spot it was supposed to in the Gulf of Mexico.
