In the 1960s, American athlete Dick Fosbury revolutionised high-jumping by inventing the 'Fosbury flop'. Instead of diving or scissor-kicking over the high-jump bar, Fosbury floated across on his back. He went on to win a gold medal at the 1968 Olympic Games in Mexico City.
In 2011, Alan Johnston spoke to Dick Fosbury for Sporting Witness.
