You can't say Elon Musk and his ventures aren't forward thinking because his SpaceX company is planning to replace long-haul aircraft flights with rocket transportation in the next 10 years. The idea is to use the BFR to launch 100 passengers on a trip to anywhere in the world within half an hour in some instances. Supposedly the cost will be around a standard business-class fare for the same distance. The cost will be low because they can reuse the rockets and launch multiple rockets everyday. Sounds good to me and I can't wait to see this happen. Shotwell announced that SpaceX will, in the next decade, launch rockets for international travel. A trip from London to Shanghai, for instance, would take as little as a half an hour, and cost somewhere around what a business-class trip the same distance would. “It’s space travel for earthlings,” she says.
