I don't disagree with your sentiment at all, but I think in this case it's not a big leap from where he was. Elon Musk has a Physics degree. All the principles are there - math, science, etc. 'Rocket science' is just domain specific knowledge in that arena. For a manager of rocket scientists, that's all he needs. Although he got his money programming code at Paypal, he was a heck of a lot closer to an aerospace engineering background than your average web startup founder today.
