Rapid Unscheduled Disassembly

 You can't have a rocket program without blowing up the occasional prototype. Unfortunately, the test flight of Starship failed four minutes after launch. The problem was failed separation.

This isn't the setback it might appear; this was a test flight of a prototype. Prototypes sometimes blow up. Space X believes it's perfectly fine to blow up prototypes, unlike NASA. On this issue, I'm with Space X, as long as you get all the blowing up done before you put any test pilots on it.

So, perhaps a slight disappointment, but it doesn't mean it won't fly.
