Drone noise an irritant? Delivery system drops packages from 150 ft by tether

A major public criticism is the noise drones make, that of a swarm of bees, and the thought of delivery craft buzzing up to their doorstep with propellers whirling dangerously close, reports newatlas.com.

A U.S Los Angeles-based company, A2Z Drone Delivery, has created a craft named the RDS1 (Rapid Delivery System 1), that incorporates a remotely-operated hexacopter that’s equipped with a motorised reel of Kevlar cord. At the end of that tether is an elastic fabric pouch that can hold a payload weighing up to 2 kg.
