amazon-patents-bizarre-accordion-like-chute-to-deliver-packages-from-its-drones.html

Looking to ever expand ways to deliver goods to its customers, Amazon has patented a way to allow its drones to deliver packages without ever having to land. The patent would not only provide a safe distance between the UAVs and the people receiving the packages, but also cut down on noise pollution, BizJournals noted. Bezos, now the world's third-richest man with an estimated fortune of $83.3 billion according to Forbes, first showed off Amazon's drone delivery unit in a Dec. 2013 interview on "60 Minutes." It recently filed patents for a beehive-like structure that would allow drones to pick up and drop off packages.
