On January 6, 1967, two Catholic pilgrimage buses plunged off a cliff near a reinforced timber bridge in the rural town of Indang, Cavite, Philippines, after colliding with each other on a mountainous road near the bridge. The accident killed more than 80 people, many of whom were women and children, and injured the remaining passengers, making it one of the worst road accidents and disasters in the world and the worst in Philippine history.
