The Ehang 184 personal drone is ready to fly

Last year the Ehang 184 autonomous aerial vehicle (AAV)—what we might call a big-ass drone—was a prototype. This year it’s a real, flying vehicle, seasoned by 200-plus successful (non-crashing) test flights, and it just may start taking passengers for real in the near future. The Ehang 184 can accommodate one person weighing up to 220 pounds
