From NBC News: It's a bird! It's a plane! It's ... more drones, potentially. The Federal Aviation Administration will announce two new unmanned-aircraft initiatives on Wednesday at the nation's largest drone convention. FAA Administrator Michael Huerta will make the announcement -- about which the FAA has not released details -- during two events at 11 a.m. and 12:15 p.m. ET at the Unmanned Systems 2015 Conference in Atlanta. "The FAA is moving ahead with safe integration of UAS into the busiest, most complex airspace in the world," the FAA said in a press briefing ahead of the event. The use of unmanned aircraft by hobbyists, companies, film directors, the military and other groups has been the subject of debate, while the FAA works to set new rules -- and clarify those already on the books. National parks have banned the use of drones, while companies including Google, Facebook and Amazon have expressed interest in the commercial possibilities. Just this week the FAA approved a commercial-use waiver for a crop-dusting drone, and massive drone maker DJI announced it raised $75 million in funding that puts the value of the company at $10 billion.
