He's talked rocket design specifics on many occasions and "built his own rocket" according to Vector Launch CEO Jim Cantrell [1]:

>He borrowed all of my college texts on rocket propulsion when we first started working together in 2001. We also hired as many of my colleagues in the rocket and spacecraft business that were willing to consult with him. ... I found out later that he was talking to a bunch of other people about rocket designs and collaborating on some spreadsheet level systems designs for launchers. Once our dealings with the Russians fell apart, he decided to build his own rocket and this was the genesis of SpaceX.

Additional info from Jim from a follow-up interview[2]:

>Cantrell ... loaned him some textbooks to study. The books were "Rocket Propulsion Elements," "Aerothermodynamics of Gas Turbine and Rocket Propulsion," "Fundamentals of Astrodynamics," and the "International Reference Guide to Space Launch Systems." He would quote passages verbatim from these books. He became very conversant in the material. ... Musk would absorb this information and then hold his own in conversations — and he didn't hold back.

Additionally, Ashlee Vance's biography [3] describes his day-to-day as "quite involved with rocket design" at SpaceX and goes into a lot of detail about spending time on the floor assisting SpaceX scientists with their designs.

Obviously any single person at a company the size of SpaceX doesn't individually design and build a rocket by themselves, but it's generally agreed upon that Elon is knowledgeable in rocket science and contributes many ideas to the designs.

They build everything in-house - software and hardware. You can read about it in detail in Musk's biography -

I'm reading his autobiography right now. Fascinating life of both the man and his companies if you are interested:

The Internet mob has only one rule: "Guilty until proven innocent".

I suspect that the turmoil has been caused by the upcoming book and its dubious marketing strategy:

As you can see from a recent thread, It's easy to fall into the clichè of drama and hubris Some users even imply he may be a sociopath.

We are not quite able to cope with the success of other people. We MUST find some kind of weakness, or tradeoff: this is why media love troubled geniuses. "Sure, Einstein was a great physicist, but did you know that [insert meaningless gossip]". It gives us the illusion of being morally superior, because of the false dichotomy between love/affection/community and money/mastery/fame.
