Here is a video clip of a Walmart-based drone delivery of items to residential home. You may have to fast forward past the half way point to get to the drone delivery.

What I noticed is how incredibly loud these drone deliveries are. These are not small consumer quadcopters but very large, heavy and loud drones.

They will be criss crossing our neighborhoods and the process of the actual package delivery can take a minute or more as the drone hovers in place.
