In japan recently, five of the hostages on the hijacked ALL Nipon Aiways flight 857 managed to make calls from the plane using mobile telephones. After the successful raid on the plane, Chief Cabinet Secretary Kozo lgarashi said the phone calls, made in secret from the aircraft’s toilets, had helped. The authorities did not know at first whether or not the hijacker was alone. This made it difficult for Prime Minister Murayama to give the go-ahead for the raid.
