RENE MARSH, CNN AVIATION AND GOVERNMENT REGULATION CORRESPONDENT: Right now, though, we should point out that drones are not allowed for commercial use unless the FAA approves it. The only other commercial drone the agency has approved is one that is flying in the Arctic. But big picture here. This is really just a small step towards that big goal of fully integrating drones into our airspace. As you know the FAA estimates, get this, in the next five years, as many as 7,500 drones could be flying in the U.S. airspace at any given time. So they want to make sure they can do this in a safe way. Carol?</s>CAROL COSTELLO, CNN ANCHOR: Unbelievable. Rene Marsh reporting live from Washington. Thank you.
