BBC NEWS | Africa | Mauritania pilot outwits hijacker: "The pilot of a hijacked Air Mauritania plane deliberately made a rough landing so passengers and crew could tackle the gunman, Spanish officials say.
He tipped off passengers about the plan after realising the hijacker spoke no French, one official told AP agency.
The hijacker was overpowered after being knocked over as planned during the landing in Spain's Canary Islands.
Mauritanian police are investigating how the hijacker boarded the Boeing 737 with two loaded handguns."
