> P.S. I'm not arguing either way on whether or not SpaceX will be safer or not than some marker. I'm sure they'll have among the safest launch vehicles ever flown. But my points so far have been 1) Beware people putting numbers or otherwise strong claims on reliability and 2) I've been trying to kick the tyres of the mental tools and reasoning people from a software background bring to bear when trying to understand things like space hardware. There is a lot more to it.
Now this I definitely agree with. I may have misunderstood your initial comment, but I was only trying to argue generally against the idea that Elon Musk is somehow out of line for saying that F9/Dragon will be the "safest, most advanced crew vehicle ever flown" because what else do you expect him to say? "We'll make it, uh, as safe as we can, I guess. Safety's a difficult concept, and rocket science is hard, y'know?"
You and I both have experience in space hardware (my guess is that you have more experience than I), so we both know how rediculous it is to put a number on things, but in this thread, we were arguing the same position from different directions. You against the sentiment of "of course it will be safe" and me against "they can't possibly know how safe it will be." Does that make sense?
