Elon Musk: Mars rocket will fly next year

During a Q&A at the SXSW festival, Elon Musk said SpaceX will be ready to fly its Mars rocket in 2019. Musk said last year that his Mas rocket, called BFR or Big Falcon Rocket, could one day fly people from city to city on Earth in incredibly short time spans, touting that it would take 30 minutes to hop from New York to Shanghai.
