Amazon is halting all commercial drone deliveries after two of its latest drone models crashed in rainy weather at a testing facility, Bloomberg’s

Amazon has paused testing of its delivery drones following a crash involving two of its models, according to Bloomberg. It's the latest setback for Amazon's beleaguered Prime Air program, which aims to deliver around 500 million packages a year to customers by the end of the decade.

Amazon confirmed that it voluntarily paused its Prime Air drone deliveries in Texas and Arizona, but downplayed the role of a reported crash of two drones in December at an Oregon testing facility as a factor in the decision.
