Amazon resumes deliveries following probe
Drones face ongoing technical challenges
Amazon’s Prime Air drone delivery program resumed operations in Tolleson, Arizona, on October 3, 2025, after pausing flights due to a collision between two MK30 drones and a construction crane on October 1. The Federal Aviation Administration (FAA) and National Transportation Safety Board (NTSB) are investigating the incident.[1][2][3]
Incident Summary
On the morning of October 1, 2025, at approximately 10:00 a.m. local time, two MK30 drones, each weighing around 80 pounds and carrying customer packages, were returning to Amazon’s Tolleson launch site when they struck the boom of a stationary crane in a commercial district near 96th Avenue and Roosevelt Street. Both drones crashed into an adjacent parking lot and caught fire. Emergency responders treated one bystander for smoke inhalation; no other injuries occurred.[4][5][6]

Safety Systems and Enhancements
The MK30 model features a best-in-class detect-and-avoid perception system designed to identify and navigate around obstacles, including dynamic hazards not visible in satellite imagery. This system integrates:[7]
Redundant flight-critical computers and sensors for single-failure resilience.[8][7]
Onboard cameras and radar to scan for people, animals, and unexpected obstacles before landing.[9]
A health-monitoring backup controller that can trigger a safe return-to-home sequence if anomalies arise.[7]
Following the collision, Amazon introduced enhanced preflight landscape scans and updated obstacle-detection algorithms to account for active construction zones and moving equipment.[4]
Prime Air Program Overview
Amazon Prime Air aims to deliver packages up to five pounds within one hour of ordering and to achieve 500 million drone deliveries annually by 2030. Key program milestones include:[10][3]
Initial FAA approval for BVLOS operations in College Station, Texas, and Lockeford, California, in 2022.[11]
West Valley Phoenix launch in November 2024, serving over 50,000 items using MK30 drones.[12]
Pending expansion into additional U.S. markets following regulatory rulemaking on BVLOS flights.[13]
Regulatory Impact
The FAA and NTSB investigations will evaluate the MK30’s obstacle-avoidance performance under real-world conditions and may inform the Department of Transportation’s forthcoming BVLOS rule for commercial drones. Industry stakeholders, including the Aircraft Owners and Pilots Association, have highlighted the need to ensure robust “sense and avoid” standards before broader airspace integration.[8][13][4]
