Google’s semi-secret R&D arm, Google X, just unwrapped its drone delivery program, called Project Wing.
During this initial phase of development, Google landed on an unusual design called a tail sitter, a hybrid of a plane and a helicopter that takes off vertically, then rotates to a horizontal position for flying around.
For delivery, it hovers and winches packages down to the ground. At the end of the tether, there’s a little bundle of electronics they call the “egg,” which detects that the package has hit the ground, detaches from the delivery, and is pulled back up into the body of the vehicle.
As a Drone fan, I do think this is a worthwhile endeavor. At the very least, this is a solid framework for getting meds or lightweight emergency gear to a rural location. Perhaps food, a cellphone or radio to a climber trapped on a mountain, that sort of thing.
