Recently, in Dubai (the largest city in the United Arab Emirates), Dubai Civil Defense started using water jetpacks that lift firefighters off the ground to hover in advantageous positions as they work the hoses. Also, using jet skis, rescuers can avoid traffic altogether by using the city's rivers to arrive at fires (and, if close enough to a waterway, can pump water without hydrants). Even more spectacularly, as early as this summer, Dubai will authorize already tested one-person, "Jetsons"-type drones for ordinary travel in the city. The Ehang 184 model flies about 30 minutes on an electrical charge, carrying up to 220 pounds at about 60 mph.
