The flying taxi is seen in Dubai, United Arab Emirates, Sept. 25, 2017. Dubai staged a test flight on Monday for what it said would soon be the world's first drone taxi service under an ambitious plan by the United Arab Emirates city to lead the Arab world in innovation. The flying taxi developed by German drone firm Volocopter resembles a small, two-seater helicopter cabin topped by a wide hoop studded with 18 propellers. Meant to fly without remote control guidance and with a maximum flight duration of 30 minutes, it comes with plenty of fail-safes in case of trouble: back-up batteries, rotors and, for a worst case scenario, a couple of parachutes.
