Another athlete who defied the existing norms was Bob Beamon when he leaped more than the distance the optical device could measure!
At the 1968 Mexico City Olympics, he leaped 8.9 metres, which was a good 2 feet longer than the existing world record! He jumped farther than the far end of the sand pit at which the optical device to measure the jump is placed. They had to take the help of tapes to finally come up with the right figure.
Bob Beamon’s jump was so good that there was even an adjective named after him – beamonesque!
