"I cannot for a second believe there is not a lot of disappointment for Elon Musk, for SpaceX," says Clarke. "This was their moment to show their prowess in efficiency, reusability, the 'fail-fast efficiency' that Donald Trump really wants his presidency to embody. "Donald Trump isn't somebody who wants to be associated with things that don't look brilliant or work amazingly." Instead, Trump wanted to be associated with Musk's glory and that hasn't happened, Clarke said. "I think that's actually going to be quite significant, despite the cheers. "This is different, this was a flight test with a political moment tagged onto it and I think it will have been not the outcome that any party wanted to see."
