There is a small city in the Northern Territories of Australia called Darwin, and it is prone to cyclone activity. It’s been hit by storms in the past, but in 1974, Darwin was pummeled by a tropical storm. From Christmas Eve to Christmas Day, Cyclone Tracy ravaged the town, killing 66 people. When at last the winds settled, 70 percent of the city’s buildings were destroyed, including 80 percent of the houses. More than 40,000 people were left without homes, and donations were set up using the slogan “Santa never made it to Darwin.” While the city was later rebuilt, Australia has never forgotten that tragedy.
