November 9, 1965 - it was a pleasant day. The evening exodus from the hearts of the great cities had just begun, when, without warning, lights in office towers flickered out and died at 5:16 p. m. Thousands of feet above, astonished airline pilots saw Manhattan fade, then disappear. In eight
minutes, a near total electrical eclipse had swept over an area slightly smaller than Great Britain but crowded with thirty million people. A massive
power failure had torn the intricate electrical grid that served parts of eight states and sections of Ontario, Canada. The Great Blackout, as it came
to be called, was the first dramatic warning that the relationship between energy supply and demand had reached a precarious balance.
You can conclude that
Canadians later withdrew from the electrical grid.
People in Great Britain began to panic when they heard the news.
Planes en route to Manhattan had to land elsewhere.
People in the area sold their homes and moved.
