Re: Brainstorming : What does it take for Urban Air Mobility to take off?

A helicopter based on drones, 5-6 electric motors 8-12 passengers, range upward of 50 miles, a pilot (for the first several years). Must be capable of landing with any 2 motors out, at least 5(?) minutes of flight available in worst possible cases. Could be hybrid but more likely not. I am confidan...
