Passengers on a Cairo-bound flight were in shock when a bizarre “passenger” — a tiny tortoise — started nibbling the toes of a young passenger on Saturday. It was shortly before Saudi Arabian Airlines Flight 317 touched down at the international airport. The control tower in the airport received a message from the plane that security men should be ready when the flight landed, as a passenger caused disarray in the plane, a source at Cairo airport said. The pet slipped from the hand baggage of an Egyptian woman while she was asleep. On seeing the creature, a woman started screaming, and others joined the chorus causing the confusion, Al-Jazirah newspaper reported on Monday.
