I remember watching that jump. I think he broke the world record by around 2 feet and not inches. He jumped over the official that was near the world record mark. The record stood for a ridiculous amount of years.
I remember seeing that picture (or something quite similar) in my 1974 Guinness Book of World Records, but it wasn’t until many years later that I saw the actual film of his performance. Dude leapt like a gazelle, unreal.
Mike Powel had that magnificent leap in 1991, but it obscured Lewis’ last two jumps, both 29’ or more. Both were amazing that night.
