Cargolux flight CV-775 had to return and make an emergency landing at Calgary International Airport, Calgary, Alberta, Canada, on May 28th.
The Boeing 747-400, en-route to Luxembourg, had to return shortly after the crew heard a loud bang followed by the stick shaker activating. It later turned out that an AoA (Angle of Attack) vane was missing.
The plane landed uneventfully.
All people onboard remained safe.
