Amazon has filed a petition with the FAA asking the agency to allow expanded testing of the company’s Prime Air drones. According to the petition, which was first reported on by CNET, Amazon has been working on improving its drones by flying them indoors in Seattle, and taking them out to other countries with more relaxed rules about where and when businesses can fly drones. However, the company can’t fly them outdoors in the U.S. because of FAA regulations that prohibit commercial use of drones. In the petition, the company asked for permission to test the drones on its own property, away from densely-populated areas, airports and military installations.
