Musk was saying it was a 50% chance the rocket blew up on the launchpad. Their sole hope was that it made it in the air, leaving the launchpad unscathed and quickly usable for future launches.
> “I'm not saying it will get to orbit, but I am guaranteeing excitement. It won't be boring,” Musk promised at a Morgan Stanley conference last month. “I think it's got, I don't know, hopefully about a 50% chance of reaching orbit.”
I stand corrected. That apparently was indeed the original context of his statement. The Internet has ways of morphing words.
I do recall he did express some level of concern about the launch pad being damaged if the rocket failed to launch though (it still looks like it was damaged to some degree from the launch.)
