I'm no fan of Musk by any means, but you only have to look at the Falcon program to see how successful Spacex has been. I have no doubt that Starship will work out.
There’s a reason words like “unsustainable” are so often associated with the Apollo program. It was amazing, but it couldn’t be a model for continued progress.
Do you consider that a failure of the Saturn-V program? Or do you understand the value of testing prototype hardware to destruction?
In SpaceX's case, they've done this exact process before with the Falcon to great success. In a few years, Starship launches will likely be a routine thing, as Falcon launches are now.
You have to understand this is a private business doing it on a budget and fast. Yes, NASA is involved...
But that doesn't seem to have been a Saturn V. What was it? I'm pretty sure it was on Youtube, but a quck search failed to turn it up.
So, maybe "not one Saturn V blew up on launch", but one of the Saturns did.
The one I'm thinking of came straight down, still vertical, nose up.
The third Redstone launch was also a lot like what you describe, but I can't find video.
There was another of the Vanguard ones where it rose a couple of inches and then shut down and fell... and survived and was launched awhile later.
Applies perfectly and seems to be working for SpaceX
