A Fort Bragg, North Carolina-based Army helicopter collided with a drone during a patrol over New York City on Thursday evening, according to news reports.
The Black Hawk was patrolling over New York City as part of a security detail for the U.N. General Assembly meeting that started early this week, Fox 5 D.C. reported.
The collision damaged the helo's fuselage and two blades. A piece of the drone was found in the oil cooler, a source told Fox 5. No injuries were reported.
Information on the drone -- who it belonged to and where it came from -- is still unknown.
Although New York City bans drones from flying in most locations, drones registered with the Federal Aviation Administration are permitted to fly above a handful of city parks.
The incident comes a month after the Defense Department formally gave guidance to all U.S. military installations on how best to address drones they deem a threat — including shooting them down.
