Well, this is nuts. If you live in certain areas of Texas, California or Arizona and have Amazon Prime, you can get same-day delivery, and this is how the packages arrive:

"The FAA has given Prime Air additional permissions that allow us to operate our drones beyond visual line of sight," Amazon writes, "enabling us to now serve more customers via drone and effectively expand and scale our drone delivery operations."

Amazon's latest MK30 Prime Air drone can fly through light rain and carry packages up to 5 pounds. The drone scored the FAA clearance because it "uses industry-leading sense-and-avoid technology that allows them to detect and avoid obstacles including people, pets, and property," satisfying safety regulators. And it typically drops the packages off "in one hour or less" from the time they were ordered.

No word on when they'll roll this out in the rest of the country; the company says they're making it available to select locations in the UK and Italy next.

Amazon says the most popular item ordered for drone delivery in the 'States is AA batteries. I wonder what it will be for the Brits and Italians.
