Amazon's delivery drones could drop packages with parachutes

Amazon's much-anticipated (and long time coming) drone deliveries might technically finally be happening, but a new patent spotted by CNN suggests your next book or box-set might actually arrive via parachute. There are many practical, legal and technical challenges that drone deliveries present -- and getting the parcel on the ground is just one of them. So far, deliveries have been carried out in relatively controlled locations where a drone can land to release its cargo. A safe landing isn't possible everywhere, not to mention other environmental hazards such as humans, pets and other obstacles. Also, this is Amazon, where efficiency is king.
