LAS VEGAS, NV - JANUARY 07: An EHang 184 autonomous-flight drone that can fly a person is displayed at CES 2016 at the Las Vegas Convention Center on January 7, 2016 in Las Vegas, Nevada. The 18-foot-long, 440-pound drone has four arms and eight propellers and can fly up to 63 mph for 23 minutes and go about 20 miles. It can carry one passenger who does not need to pilot the drone. Once a destination is entered, only a take off or land button needs to be pushed to travel. The drone takes off and lands vertically eliminating the need for a runway. CES, the world's largest annual consumer technology trade show, runs through January 9 and features 3,600 exhibitors showing off their latest products and services to more than 150,000 attendees.
