unhistorical:

Greatest Olympic Moments: Bob Beamon, Mexico City, 1968.

So incredible was Bob Beamon’s long jump (8.90 meters, or 29 feet and 2.5 inches) that the athlete himself collapsed and broke down after realizing that he had shattered the previous record by nearly two feet. His world record stood until twenty-three years later, when it was broken in Tokyo, but to this day, Beamon’s “perfect jump” remains the Olympic record.
