Amazon has suspended testing of its delivery drones following an accident involving two of its models. according to Bloomberg. It’s the latest setback for Amazon’s embattled Prime Air program, which aims to deliver about 500 million packages a year to customers by the end of the decade.
Bloomberg reports that two Amazon drones crashed in rainy weather at a testing facility in Pendleton, Oregon, in December. In another incident in September, drone operators employed by the company were testing how the drones would behave if one of their propellers failed, according to Bloomberg, and accidentally launched two test flights at once, causing the drones to collide. .
Amazon said it would suspend drone deliveries in Texas and Arizona, where it has commercial drone operations, pending a software update for its drone fleet, according to Bloomberg.
Amazon’s drone program has faced numerous setbacks, including the departure of key executives. Last April, Amazon ended Prime Air drone delivery operations in California, although the company plans expand its drone delivery tests abroad.
