The pilot of the Cessna jet radioed air traffic controllers to warn them that “A remote controlled aircraft” had flown past his plane far too close for comfort.
“Something just went by the other way … About 20 to 30 seconds ago. It was like a large remote-controlled aircraft.” the pilot said in the transmission that was captured on the live air traffic audio website liveatc.net.
The craft was reported as being about 8,000 feet above sea level, or about 2,800 feet above the ground, at the time the pilot reported the seeing it. It did not show up on radar.
The type of drones used by NATO typically fly at 10,000 feet and below. Other tactical military drones can fly up to 18,000 feet.
