> 1 in 23 flights resulting in booster loss due to an uncontrolled fire is not good enough for human space flight. The space shuttle had a catastrophic failure rate of 1 in 67 flights I think your numbers are a bit off. The space shuttle had a failure rate of 1 in 67 as a whole program, using multiple vehicles. The 1 in 23 is just that single booster. Before this failed landing they had 267 consecutive successful landings. From the numbers I’m seeing online Falcon 9 has launched 377 times and had 374 successful missions so the failure rate is 1 in 126 EDIT: I’m not going to comment on the rest of your comment because you went all over the place grabbing data at random to try justify your view.
