I was curious about that 6.5 mile claim, and you are correct - while large chunks were thrown thousands of feet away, the plume of concrete dust expanded 6.5 miles away.
Knowing him, Musk is behind all the safety flaws of the last launch. The engineers were probably very aware of the issues, but Musk told them to go ahead because obviously he knows better.
And it's pissing me off because Starship itself is an innovative new idea but he's gonna end up driving it into the ground before it even has its first real mission. I've been waiting 35 years for somebody to attempt to go to Mars since I was 5, and I'd like to still see at least ONE human landing before I die.
They knew it would happen. The engineering here is well established and has been for decades. Musk even tweeted that not having a flame diverter “might be a mistake”. Willful negligence.
Pretty sure it was intentional. I can't find it now but there was a decision by Elno to not add the water systems to the launch pad which would have prevented the pad from being destroyed. They knew it would get damaged so decided not to mitigate the problem.
Indeed. They were planning to rip out and replace the pad anyway, and believed that they'd at least get one launch out of the existing one, so they saw no reason to delay. If they'd waited for the new pad to be installed they would only just be gearing up for their first test flight right now. They've had four months to refine the rocket's design based on the data they got from the first test launch.
They misjudged the robustness of the original launch pad, but only somewhat. IMO the much more serious misjudgement was their flight termination system, they blew holes in the ship's tanks when it started tumbling out of control and it took something like 40 seconds for the ship to finally disintegrate after that. That was a situation where they underestimated the robustness of their systems. The new flight termination system is much more powerful.
I mean, one of the main proximate causes of the failure to achieve orbit was that the concrete rebounded into the engines because Musk thought they could get away with not using blast mitigation
