“The way rockets work right now is they are all expendable. So, you fly them once, and you throw it away. You can imagine if any mode of transport was expendable, it wouldn’t be used very much. But whether it’s a plane, a boat, a car, a bicycle, or a horse – they’re all reusable. If a 747 costs about a quarter-billion dollars and you need two for a round-trip, nobody is paying half a billion dollars from London to New York and back.”
