> Except SpaceX’s failure rates are similar with every other successful launch system

Really? I make is 189 successful F9 launches since the last issue in 2018 (there's a couple of landing failures, but given that everyone else apart from the space shuttle has a 100% loss...)

If you look at the "finished product" of block 5 that makes 162 launches and zero failures.

That's reliability far beyond any other launch system, including the space shuttle and Ariane 5 which are the only ones to come close in numbers of launches. Ariane 5 is certainly a reliable system as far as spaceflight goes, but it flies 3 times a year, Falcon 9 flies 3 times a month

Landing the shuttle is like landing the Dragon Crew capsule. SpaceX landed the booster, where shuttles ditch theirs into the ocean.

So even shuttles have a pretty high loss rate :)


Hardly, landing on launch pad had a lower success rate and requires significant fuel so many otherwise perfectly reusable boosters were sacrificed for a higher launch payload.

They got great publicity from it, but landing vertically is a major compromise.


Sure, ignoring past failures can always make someone on a winning streak look invincible. But calculating the underlying odds to hit even a 200 long winning streak with the observed failure rates on other systems wouldn’t be particularly unlikely.

These systems all are quite good, and they have tended to get better over time.


There's no evidence that anything other than Ariane 5 and Falcoln 9 are "quite good"
