I had many people try to convince me not to start the company. I mean, if there was anything they could have done to stop me from starting the rocket company, they would have done it. So, that's when I decided to start the rocket company. >> Musk is no rocket scientist. He's a dotcom millionaire. >> Not knowing anything about rockets, not having ever built anything. >> Now, he says he can do what NASA has not. >> I would have to be insane if I thought the odds were in my favor.

Just moments after takeoff, the rocket failed. >> Yeah. 2008, we had the third consecutive failure of the Falcon rocket for SpaceX. >> Yeah, this is bad. >> We were running on fumes at that point. We had virtually no money. >> Can we just break for a second? >> Sure. Sure. Of course. >> The great thing about Elon is that he understands that failure is part of the development. >> Did you think I need to pack this in? >> Yeah. >> Why not? >> I don't ever give up. There's a much bigger picture in Elon's mind some way or another all goes together. >> Critics say you can't do this. Your answer to them is we've done it. >> This is the best entrepreneur of our generation and he's going after two of the biggest markets of all time. This is classic Eli. >> We want to be able to take anyone who wants to go to the moon, anyone who wants to go to Mars. We want to be able to take you there. Not just a few astronauts. I mean you. It would be the greatest adventure ever in human history. >> It really is really hard. >> So, rocket science really is rocket science. >> Yeah.
