The first time we heard about Prime Air it was emblazoned on drones Jeff Bezos showed off for 60 Minutes in 2013. Now Amazon is revealing the logo on a flying machine that operates on a much larger scale. Amazon One is just one of its 11 dedicated planes, and the Boeing 767-300 will be flying this weekend at a Seattle airshow. The company says that maintaining its own air cargo network -- the planes are leased from shipping partners, with plans to expand to 40 over the next couple of years -- will help it keep shipping speeds up.
