Your next Amazon product may just be delivered to your doorstep from the skies.

In what seemed as a farfetched idea at first, Amazon is getting closer to achieving its goal of delivering products to people from the skies after receiving an experimental airworthiness certificate from the Federal Aviation Administration (FAA).

According to Amazon, the certificate will be used for development, research purposes as well as training their crew.

The certificate which was issued to Amazon will see them fly their drones at 400 feet or below. In addition to that they should see to it that they only fly their drones during daylight hours and they should always see to it that they stay within sight of the pilot. In the U.S. flying drones for commercial purposes is illegal, however those laws are currently being reviewed by the FAA which looks like it will be issuing out new laws that will see the operation of unarmed aircraft for recreational and commercial purposes legal.

Amazon has been pursuing this goal for a very long time now, with its first request to test their unmanned aircraft coming last July. Back in July 2014, the company’s vice president of global public policy, Paul Misener, wrote a letter to the FAA stating that, “Without approval of our testing in the United States, we will be forced to continue expanding our Prime Air R&D footprint abroad.”

In addition to the rules that Amazon have been given with regards to testing their unmanned aircraft, they will also be required to submit monthly data with regards to the number of flights which have been conducted as well as any other useful information.
