You ignored that his Obama buds got to pick the winners and loser. Musk was a big Obama donor. That aside, I admit I am not sure what to think of a company that came out of basically nowhere and swept 60 years of launch industry aside. On the one hand, they have some good young folks working for them. On the other hand, they dont have the historical knowledge or lessons learned yet, and they have to relearn those at tax payer expense. Anyway, as I have said more than once now, I hope it goes well today.
Just FYI, SpaceX has no few very angry old engineers from the DC-X and Rotary Rocket programs too. Its not just new guys and gals but people who are still angry about NASA forcibly stifling private space flight from the 80s through the 2010s to protect their precious Shuttle.
