Even crazier, they were saying it would be vastly cheaper and faster than air freight and would probably eliminate the need for most transoceanic air freight.
Vastly cheaper... it sounds like not an optimal approach energy-wise, so maybe not so easy.
Need for transoceanic air freight - maybe, after the whole infrastructure is in place. If we'll see that, it might take a while - like, not this decade at least :) - to achieve.
Also, Starship doesn't need pilots, so freight transport could be automated.
On the other hand, I wonder about noise emission. Probably much louder than planes.
