Amazon’s drones won’t be making any deliveries in the near future. According to BloombergThe company halted all commercial drone deliveries in Texas and Arizona after an undisclosed incident in which two of Amazon’s MK30 drones crashed at the Pendleton, Oregon airport it was using for testing. MK30 is the company’s next-generation drone model, which is lighter and has a longer range than its predecessor, the MK27. The incidents happened in December, where one of the drones caught fire after it fell. Amazon has reportedly determined that its drones crashed due to a software issue linked to light rain during the tests.

The company said, however, that the crashes were not the “main reason” why it stopped delivering drones. Amazon spokesman Sam Stephenson said Bloomberg that it is “currently in the process of making changes to the drone’s software” and that the cessation of operations is voluntary. After completing the updates, Amazon still needs to get approval from the Federal Aviation Administration before it can resume its operations. “Employees at the drone sites, who were told of the action on Friday, will continue to be paid during the outage,” Stephenson added.

In addition to the crashes in December, two MK30 drones collided in another test a few months ago. Stephenson explained that Amazon expects to see incidents like this during testing and that it will help the company improve the safety of the service. Amazon has been sending non-medical deliveries via drones to Texas since 2022 increase in prescription medication a year later. In 2024, Amazon stopped drone deliveries in California, but this too Cebu launched the service in Phoenix, Arizona.
