Tangential, but I've wondered about the opportunity for a company like Fedex to send freight on rockets between Fedex's major hubs, like Memphis to Guangzhou, so that you could get literal 'next day' service to the other side of the globe. Obviously very expensive, but also, at just $2,200/lb, there might be plenty of things that would be viable, like rushing an organ transplant or delivering an iPhone prototype, cutting out the 14-16 hour flight from Memphis to Guangzhou. Surely there are some scenarios where it starts to make sense, even at $10,000/lb
