November 9, 1965
Nov. 9th, 2021 08:44 amToday is the 56th anniversary of the Great Northeast Black-Out! Misptogramming in a Queenston, Ontario power plant near Niagara Falls set off a series of relays that affected the entire Northeast power grid. Oh, and some people claim seeing a flying saucer hovering over the Niagara Falls power plant just before the black-out. ;)
The northeast blackout of 1965 was a significant disruption in the supply of electricity on Tuesday, November 9, 1965, affecting parts of Ontario in Canada and Connecticut, Massachusetts, New Hampshire, New Jersey, New York, Pennsylvania, Rhode Island, and Vermont in the United States.
Wikipedia gives a good explanation of the cause.
Darkness everywhere! People relied on transistor radios to give them the news. As eerie as The Twilight Zone episode, The Monsters Are Due On Maple Street. ;)
