Ireland

The crew was performing a ferry flight from Goose Bay to Belfast-Nutts Corner Airport. While approaching Ireland, the navigator informed the captain that the fuel reserve seems to be insufficient to reach the destination while the radio operator was unable to contact ground. The captain was approaching St Angelo but the airfield was closed due to fog and clouds so he decided to fly back to find a clear zone near Ballyshannon for an emergency landing. After touchdown, the bomber hit a concrete wall and was wrecked. Eight crew members were injured while two others were killed.
