What happened

Two Amazon Prime Air MK30 delivery drones crashed during test flights in light rain at Amazon's drone test facility, four minutes apart, after faulty lidar readings (made more rain-sensitive by a software update, with no backup 'squat switch' landing sensor as on the prior MK27 model) caused the drones to falsely believe they had landed, shutting off propellers mid-air at 217 ft and 183 ft. Amazon paused Prime Air commercial deliveries in College Station, TX and Phoenix, AZ to fix the software.
