Elon Musk: Cost per seat should be about the same as full fare economy in an aircraft. Forgot to mention that.

Really? I'm surprised. Well then...


I think the key difference is if you're designing specifically for travel on earth then supersonic jets probably are much cheaper.

However, if you're designing for space and can allocate the R&D costs to space business units, you end up potentially developing something that has better marginal costs to transport people across the earth.

Basically, the R&D of building this is astronomically higher than the supersonic jet. But the (theoretical) promise is the marginal cost isn't that different. However, if you're already doing the R&D for other purposes, then you find yourself owning a system that's (potentially) better for global travel.
