People will soon be able to fly from city to city within minutes, rocket and car entrepreneur Elon Musk says. Mr Musk made the promise at the International Astronautical Congress (IAC) in Adelaide, Australia. Mr Musk told the audience he aimed to start sending people to Mars in 2024. His SpaceX company would begin building the necessary ships to support the mission next year. He says he is refocusing SpaceX to work on just one type of vehicle - known as the BFR - which could do all of the firm's current work and interplanetary travel. As well as being the CEO and chief designer at SpaceX, Mr Musk also founded the Tesla electric car company and is chairman of SolarCity which specialises in renewables technologies, such as high-storage batteries.
