Amazon (NASDAQ:AMZN) has restarted drone deliveries in two states after a months-long pause, the company confirmed.
In January, Amazon halted Prime Air deliveries in College Station, Texas, and Tolleson, Arizona, the two U.S. markets where it’s testing the service, as the company rolled out a software update to its drone fleet.
Amazon discovered an abnormality with the drone’s altitude sensor, caused by dust in the air, that could have caused its system to produce an inaccurate reading of its position relative to the ground, the company said. Amazon “never experienced an actual safety issue,” but said it opted to suspend deliveries while it corrected the issue.
The company brought drone deliveries back online last week after it completed the software update and received approval from the Federal Aviation Administration, Amazon spokesperson Av Zammit said in a statement.
“Safety underscores everything we do at Prime Air, which is why we paused our operations to conduct a software update on the MK30 drone,” Zammit said. “The updates are now complete and were approved by the FAA, allowing us to resume deliveries.”
Zammit said Prime Air has seen “unprecedented levels of demand” since it resumed service. David Carbon, an executive who oversees Amazon’s drone program, wrote in a LinkedIn post last week that the company dropped a bottle of ZzzQuil sleep medicine at an Arizona customer’s home in “31 minutes and 30 seconds.” Carbon didn’t say how far the drone had to fly and Zammit declined to provide details.
