Online Public Relations Thoughts

This is thinking beyond the normal way of doing things.  It's still far too early to know if the drone-robot combination will work and is cost-efficient.  Such far out ideas can easily fail and it is still open whether the world needs such high-tech delivery of packages.  The test is attracting publicity, but it is a big step away from day-to-day consumer activity.  Many have tried aerial and ground delivery and so far, none have worked well.  There is no guarantee this time will be different.
