[6] At the time, customers participating in the trials were required to install a physical marker in their backyard to specify the drop-off location, and to designate a person responsible for observing the drone's flight path.

[9] As of 2023, U.S. FAA Part 107 regulations required drones fly no higher than 400 ft. (122 m), no faster than 100 mph (161 km/h), and remain within the pilot's line of sight.

[9] In June 2019, the FAA granted Amazon Prime Air a Special Airworthiness Certificate for training and research of its MK27 drone.

[12] The same year, Amazon began trials in several rural areas in Oregon and California, which were still ongoing as of April 2022, with about 30 different products available for delivery.

In 2017, Amazon was granted a patent for a method that would allow autonomous cars to deal with reversible lanes by receiving information from a central management system.

[13] On June 13, 2022, Amazon announced that they would be delivering products using Prime Air drones to customers residing in the small town of Lockeford, California.

[14] The announcement did not provide a specific launch date other than "later this year", as Amazon was still awaiting permission from the FAA and Lockeford officials.

College Station City Council approved a zoning change to allow Amazon to put its Prime Air facility in July 2022.

[19] In October 2023, Amazon announced that drone deliveries will start in the United Kingdom and Italy in 2024, beginning in one site and then expanding over time.
