This Physical Package Protocol

In 2011 I invented the Physical Package Protocol concept, originally called Pigeon Post.  The core of the idea is a way of sending and delivering packages using a network of autonomous quadcopters, public transport infrastructure and private vehicles.  It has many advantages over the current vehicle and human system as well as advantages of point to point drone bases systems envisioned by Amazon and delivery companies.
