A commercial light airplane has collided with a drone in Quebec, Canada, causing only minor damage as the jet descended for landing at the Jean Lesage International Airport.

The incident occurred three miles from the airport, at 1,500 feet. It is illegal to fly drones within 3.4 miles of airports in Canada without special permission.

Greg McConnell, chairman of the Canadian Federal Pilots’ Association, said the incident “was just a matter of time. There are a lot of drones flying, and there are a lot of people flying drones thinking they’re toys.”

Canadian transport minister Marc Garneau said “it could have been much more serious … aircraft are particularly vulnerable when on final approach coming in — the pilot is concentrating on landing properly.”

A sharp increase in pilot sightings of drones has led to a warning from the US Federal Aviation Administration, which noted that “operating drones around airplanes and helicopters is dangerous and illegal.”
