“After being inactive for two months, Amazon’s drones are once again taking to the skies.

Amazon confirmed to CNBC on Monday that it will resume Prime Air drone deliveries in the two U.S. areas where it is testing the service: College Station, Texas, and Tolleson, Arizona.

Amazon stopped drone deliveries in the two states in January after detecting issues with the altitude sensors of its 80-pound MK30 drones. Dusty air in the two cities had the potential to interfere with the drone’s altitude readings, creating a safety risk.

Amazon said on Monday that it did not experience any safety incidents in flights from the altitude sensor, but it took the precaution of stopping deliveries until it had rolled out a software update to fix the issue. As of last week, Amazon completed the update and received a stamp of approval from the Federal Aviation Administration to resume operations.”
