Overview

• Two Prime Air MK30 drones struck the boom of a construction crane in Tolleson around 10 a.m. on Oct. 1, with no serious injuries reported and one person treated for smoke inhalation, according to local reports.
• Federal officials from the FAA and NTSB launched investigations, and preliminary FAA reports described substantial damage to the drones during mid-route operations.
• Tolleson police said the drones were flying back to back and both impacted the extended crane, with wreckage found in separate parking lots roughly 100 to 200 feet apart.
• Amazon briefly paused Prime Air flights in the West Valley before resuming service Friday, saying it will continue cooperating with federal reviews.
• The MK30 aircraft used in Tolleson can deliver packages up to about five pounds; the program has faced prior pauses after test-site crashes in Oregon that led to software updates earlier this year.
