Google on Thursday said it is testing using drones to deliver items bought online, putting its own spin on similar efforts by Internet retail titan Amazon.com. Two years of research into what Google referred to as Project Wing was capped this month with test flights delivering candy, water, medicine, dog treats and other items to two farmers in Queensland, Australia. Self-flying vehicles could open up entirely new approaches to moving goods, California-based Google said in a blog post disclosing the project. Project Wing drones were described as having more in common with Googles self-driving car than remote-controlled aircraft used by hobbyists.
