November 12

1955 - Hill Valley lightning storm.  Marty McFly uses lightning to power a time machine to go to October 26, 1985.  Shortly before, Emmet Brown was inadvertently sent to January 1, 1885 in the same (though slightly more aged) time machine.  Much earlier in the day, Biff Tannen arrived from and returned to October 21, 2015.
