Customers compare the noise from Alphabet spinout Wing's delivery drones to a chainsaw

Wing, a graduate of Google parent company Alphabet's X R&D lab, aims to develop drones that might one day be used to deliver packages to customers' doorsteps. According to The Wall Street Journal, Wing's parcel-carrying drones, which were deployed in a rural area of southeastern Australia in October 2017 as part of a pilot program, have disrupted the lives of some longtime residents, who say that they don't use their yards as much. And the noise -- which some accounts compared to that of a chainsaw -- tends to spook pups, a local dog club president told the publication. The current-gen Wing drones can fly at speeds of up to 78 miles per hour and take off and land vertically, thanks to a dozen vertical rotors and two propellers. Automated flight-planning software determines their route, while onboard sensors help them to avoid obstacles. Despite the sophisticated onboard tech, though, sounds aren't the only problem Wing's drones have yet to overcome.
