Your excellency, the most exalted mr. purple cat esq, the illuminated one and holder of the sacred chalice of Zynbax,

What, in your opinion is the 'right' way to get stuff into space if we're going to make it a commercial enterprise where we're shipping stuff up on a daily basis?

I'm queuing up Kerbal to test your theories.
