These teachers have the world's most perilous commute - tip-toeing across a rickety rope bridge hanging above a raging river. Staff at the Baja Elementary School in Calbayog, Philippines, have to cross the fast-flowing muddy river every day to reach classes. Footage taken last Friday (05/01) shows how teachers have to hold their papers under one arm while inching their way across the tatty old bridge made from rope, wire and wood.
