New York blackout

In 1977, a power failure blacked out New York. Starting at about 9 pm, four lightning strikes on high-voltage transmission lines within the course of about half-an-hour knocked out electricity and plunged millions of residents of New York City into darkness. Unlike the calm during a similar blackout in 1965, the 1977 blackout erupted in chaos. The city was already in the midst of a financial crisis and high unemployment. Responding to the tension of the times, mobs set fires, smashed windows and hauled away food, clothing and appliances. It took 25 hours to restore power to the entire city. About 4,500 people were arrested during the riots, which resulted in damage estimated at $61 million.
