Well, he should have a good supply of people with aerospace experience in this area.
I have more faith in Bezos than I do with Musk... He is doing it slow and I like his long term goals..
Not sure there are many aerospace engineers left in the area with the 787 ramping up.
But that said, if people like Bezos and Paul Allen with SpaceShipOne and Branson with Virgin Galactic are placing bets on these ventures, I think these ultra-bright ultra-successful entreprenurs have something going! Do you know if they are offering any public stock? LOL!
