Before Amazon suspended drone deliveries, the MK30 crashed in two separate incidents during test flights at the company's facility in Pendleton, Oregon. Last December, a software issue caused two drones to crash, according to Bloomberg. And in September, a pilot mistakenly caused a "mid-air collision" between two drones after he tested how the MK30 would perform when faced with a failed propeller, according to a federal crash report.
Another crash occurred on Feb. 21 during tests at the Pendleton site, which resulted in a drone sustaining substantial damage, according to a report compiled by the National Transportation Safety Board.
