I agree, here's the comparison of what BO is doing compared to SpaceX. http://i.imgur.com/Z81NgAk.png
> But getting to space is easy. The problem is staying there.
> To avoid falling back into the atmosphere, you have to go sideways really, really fast…The speed you need to stay in orbit is about 8 kilometers per second. Only a fraction of a rocket's energy is used to lift up out of the atmosphere; the vast majority of it is used to gain orbital (sideways) speed.
Highly recommended.
