           | if collides with something during descent or ascent. Overall,
           | a very clever design that should be safer, create no noise on
           | ground level, and be able to deliver into much smaller and

             | to keep them out of reach of the employees. Probably even
             | touted as a safety feature. I just haven't seen the system

       | That being said, drone delivery will not really become a thing
       | unless the endurance issue is resolved, like a new breakthrough
       | battery technology that gives you at least 4 hours flight time

             | Edit: The Internet tells me that delivery drones fly at
