The Federal Aviation Administration has released new information that sheds light on the number of drones filling American air space.
Two incidents involving drones were reported in North Texas in the summer of 2015, but the FAA suggests drones have become a daily nuisance at airports across the U.S.
Pilots reported seeing 238 drones near their aircraft in 2014, but that number skyrocketed to 650 reports by Aug 9, 2015. In many cases, the pilots are spotting the drones in their final descent to land, or just after takeoff.
Aviation experts said it is a tough problem for law enforcement to tackle.
"The problem that comes with this for a lot of law enforcement involves locating the people flying the drone and catching them in the act, so to speak," said Denny Kelly, a Dallas-based aviation expert.
The FAA report said 138 pilots reported seeing drones at altitudes of up to 10,000 feet during the month of June, 2015. That number reached 137 in July, 2015.
A website laying out restrictions and drone regulations was established to help drone users operate within the rules -- which include flying below 400 feet and to not interfere with manned aircraft.
