But Jeff Holden, Uber’s chief product officer, does not exclude the possibility that the firm may at the outset own some aircraft, which he estimates will cost around $1m each.
The firm plans to have a prototype of its service ready by 2020.
The firm rather optimistically promises that the cost per aerial mile for passengers will be roughly that of its low-cost car service, UberX.
How to oversee and license the new aircraft, which are subject to much tougher rules than cars, will be a subject of intense debate among rule-makers, who tend to move slowly and are just getting to grips with drones.
