Amazon drone delivery has taken flight in the West Valley of metro Phoenix with its new Prime Air service. The online retail giant is now offering drone delivery to select Phoenix-area residents living near its same-day delivery warehouse in Tolleson, Ariz, Amazon announced last week.

Amazon is reportedly developing smart glasses for its delivery agents that will help them with directions during deliveries.

The glasses for delivery drivers would expand upon the audio-only Echo Show by including a small embedded display that could give drivers turn-by-turn directions as they’re locating a home or apartment.
