If you track a parcel on its way to you from the other side of the continent, you will watch it meandering around an extremely indirect route. You would think with automated sorting equipment and so many flights and trucks it should be possible for parcels to go pretty well directly to their destinations. Instead, UPS (Uninterruptible Power Supply) for example takes all its parcels to one central point, sorts them, then fans them out to their destinations and makes no use of any flights but its own.
