The International Athletics Federation, World Athletics, has approved the listing and now Shinnick is mentioned as one of those who held the world record.
It was at a competition in California on May 25, 1963 that Shinnick jumped 8.33, which was then a world record of two centimeters.
Due to the lack of anemometers, the record was never approved.
After the competition, there were various tasks, partly those who talked about strong tailwinds and partly those who said that it was basically windless.
- I saw the hope and it was under approved conditions, competition leader Tom Moore said.
Improved the personal record by 58 centimeters
Until the competition, Shinnick was quite unknown and had a personal record of 7.75.
He has been trying to get the hope approved for decades.
In 2003, the United States Athletics Federation approved it as a national record at the time.
He participated in the Olympics in 1964 and 1968.
So now WA has approved it globally.
To celebrate, Shinnick was invited to the US Olympic qualifiers in Eugene, Oregon, last week and received a plaque for the feat.
It was the current world record holder and double world champion Mike Powell (8.95) who handed it over.
Sweden's best long jumper Thobias Montler has jumped 8.13 this year.
