During August’s OppiKoppi Music Festival, attendees can order beers from their phones to be delivered the event’s District 9 campsite. The beer-equipped drones will swoop down and deliver beer via parachute to the appropriate customer, as explained in the video above. The organizers say the beer drones are now hand-guided, but in the future they’ll fly on a GPS grid. But this 21st-century service might not fly without its share of turbulence: Targeting the right customer amongst the crowds at OppiKoppi will be an interesting challenge to overcome. And festival attendees might not have the greatest sense of motor control for catching their drink order, after having one too many.

This idea leads to several interesting possibilities.  Pizza and other foods delivered to your home (or current location), Amazon, Fed Ex, UPS and USPS deliveries.
