The buzz about Amazon using drone technology to speed delivery will
quieten down a bit after this construction of a roadblock:

If I understand it right, Santa will be able to continue to do
miraculous deliveries, since he pilots the sleigh himself and it's
always in his plain sight.  My recent experience of Amazon suggests
that they are closing in on Santa but not quite there yet, with next
day delivery on Sunday already happening but my one experience of
same-day delivery turning into two weeks of phone calls to their
outsource delivery service called LaserShip, whose lasers appeared to
be seriously misaligned.
