An engine shutdown is being blamed for an Air Canada flight to Alaska being forced to return to Vancouver on the weekend.
The airline says the Airbus A320 had left Vancouver for Anchorage when it encountered a problem with one of its engines.
The plane turned around and landed safely in Vancouver where passengers were put on another plane.
Air Canada says planes are designed to fly on one engine and pilots are trained for such situations.
There were 112 people on the flight.
The airline says the plane was taken out of service for maintenance.
