Can’t wait till this style of delivery method is available. Tested had a first hand look at the Google Project Wing Delivery Drone Prototype. Not that it will have a direct replacement for things such as pizza delivery since the payload needs to currently be quite small but the flight and delivery method is great. Scaling these up to handle larger packages would make it great for package delivery directly into your secure back yard in minutes. I guess the only concern people will have is what happens when something goes wrong and it falls from the sky and knocks someone in the head.
