Amazon's new MK30 Prime Air drone is displayed during Amazon's "Delivering the Future" event at the company's BFI1 Fulfillment Center, Robotics Research and Development Hub in Sumner, Washington on Oct. 18, 2023. Amazon is facing federal probes after two of its Prime Air delivery drones collided with a crane in Arizona, prompting the company to temporarily pause drone service in the area. The incident occurred on Wednesday around 1 p.m. EST in Tolleson, Arizona, a city west of Phoenix. Two MK30 drones crashed into the boom of a stationary construction crane that was in a commercial area just a few miles away from an Amazon warehouse. One person was evaluated on the scene for possible smoke inhalation, said Sergeant Erik Mendez of the Tolleson Police Department. "We're aware of an incident involving two Prime Air drones in Tolleson, Arizona," Amazon spokesperson Terrence Clark said in a statement. "We're currently working with the relevant authorities to investigate." Both drones sustained "substantial" damage from the collision on Wednesday, which occurred when the aircraft were mid-route, according to preliminary FAA crash reports. The Federal Aviation Administration and National Transportation Safety Board are investigating the incident. The NTSB didn't immediately respond to a request for comment.
