Bob Beamon broke the world's long-jump record at the 1956 Summer Olympics in Australia with an astounding jump of 9.76 meters. However, it was invalidated due to the assist that he received from an impending cyclone's sudden high winds, which cancelled events for the next 3 days. He did not break the record again until 1968 with 8.90 meters, though he held it until 1991.
