This will be a huge issue, even if Amazon gets this through the FAA, there are going to be all kinds of local interests expressing their concerns. What happens when one of these gets tied up in an overhead power lines? Did folks living near the fulfillment centers (assuming the warehouse were there first) sign up to live near a heliport, with dozens+ of aerial noise sources buzzing off every day? What about trees, etc? This looks cool, and Amazon has some smart folks so this will likely work itself out over time, but there is going to be a lot to overcome.
