70,000 supposedly witness this event in 1917.
"All of a sudden the clouds "drew apart like curtains" to reveal the sun which appeared as a pale silver disc. The sun began to spin wildly in the sky for a couple minutes and then came to rest. Then the cycle repeated two more times. The third time the spinning ended with the sun crashing toward the earth. People fell to the ground expecting to die. Then the sun returned to its normal position. (Present day skeptics, who try to discount the miracles of Fatima by human rationalization still cannot account for the bizarre actions of the sun that day; historically documented. Nor can they explain how this event was prophesied correctly in advance.) "
