Pilot reports drone sighted near JFK airport: FAA

US aviation authorities said Tuesday they had opened an investigation into a pilot's sighting of a small unmanned aircraft in the air near New York's John F. Kennedy International Airport.

The Federal Aviation Administration said an Alitalia pilot reported seeing "a small, unmanned or remote-controlled aircraft while on final approach" to land at the airport on Monday.

The sighting was approximately four to five miles (six to eight kilometers) southeast of the airport "at an altitude of approximately 1,500 feet," the FAA said.

It added that the pilot did not take evasive action and the Alitalia jet landed safely.

"We saw a drone, a drone aircraft," the pilot can be heard in a radio communication to the control tower, picked up and disseminated by the website LiveATC.net.
