Amazon lands patent for delivery drones that can be waved down by customers

If Amazon's delivery drones do actually enter our lives, what will they look like and how might they move around? Will they launch from moving trains or blimps? Will they recharge on lamp posts and self-destruct in midair? If the latest patent issued to the company is anything to go by, perhaps they will be waved down by customers awaiting deliveries.

Amazon filed the patent for a drone system that would allow for human interaction with unmanned aerial vehicles back in July 2016, and was awarded it by the US Patent Office last week.
