1/100 is absolutely terrible. Shuttle had 1.5% failure rate. Bonkers.
[edit]
For comparison, commercial aviation has something like 1 in 5.8m or 6x 9's of reliability.
It's not terrible for space flight. Flying a rocket to the moon and commercial aviation are obviously very different things.
There have been 412 manned space flights, ever, by anyone, anywhere.
A large commercial airport handles many times that number of flights every single day. Worldwide there are a hundred times more flights per day than the number of manned space flights in history.
I suspect every model of commercial plane has flown far more flights than all the human rated rockets put together.
