By the end of 2022, spaceX was preparing for a key test ,starships first test flight using both parts of the racket. Musk said the year before that there was lot of risks associate with the first launch

I would not say like ,it is likely to be success , but I think we will make a lot of progress .

The plan was for starship to take off from the launch part in Texas . The boost would then separate and fall into the Gulf of Mexico as the spaceX engines fired and took it in a 90 minutes flight . Then it would come down ,and crash in the pacific ocean , but that’s not what happened ,shortly after starship launched at 9,33am eastern . A graphic on the live stream indicated that three engines were not working . With more appearing to go out before the blast .

The shutter that was intended to separate from booster here . Didn’t

After climbing 24miles , the racket began to tumble back to earth , and around 4 minutes into its flight , starship explored .SpaceX said a flight termination system was triggered on both this spacecraft and the booster .

When you have a failure ,you learned a lot from that failure . So I think their plan was to test to the point of failure ,and then let’s learn from what we can from that failure ,so it never happens again .
