On November 9, 1965, over thirty million people in the Northeastern region of the U.S. and Canada were plunged into darkness in what became known as the "Big Blackout."The official cause of the huge outage shifted from one explanation to another, until it was finally pinned on an unknown power surge that occurred at a generating station north of Niagara Falls. But what could have caused this huge wave of electricity (reportedly 1.1 million kiowatts) that led to a relay malfunction?
Interestingly, there were a number of documented UFO sightings in the area proceeding and during the blackout. For instance, a pilot who safely landed a plane in the darkness at the airport in Syracuse, said he saw an enormous ball of light drifting in the sky. Around the same time, a flight instructor and a student who were in the air, also saw the object and pinpointed its location to be directly above the Clay sub-station, which was where the original investigation of the blackout began.
The late Dr. James MacDonald, a noted researcher and physicist has contended that UFOs may be surrounded by strong magnetic fields which could cause power surges, and lead to a massive blackout. For more on this story read the article(1) from UFO Canada by Yurko Bondarchuk.
