Someday, commercial drones might become so prevalent, it would be impossible to look up without seeing at least one in the sky. NASA and a number of drone enthusiasts believe that in order to keep those UAVs, well, orderly and away from restricted locations (here's a tip: don't fly near the White House), a traffic management system has to be in place. That's why the space agency and the Association of Unmanned Vehicle Systems International (AUVSI) are hosting a convention on July 28th to 30th where they can all discuss the topic. Both NASA and FAA execs will be in attendance, along with UAV users in film, agriculture, academia and other industries.
