At the 1968 Summer Olympics Bob Beamon jumped 8.90 m (29 ft 2 1â4 in) at an altitude of 7,349 feet (2,240 m), a jump not exceeded for 23 years, and which remains the second longest legal jump of all time.
Dana now maintains a company that produces high dive shows. He was tied with the world record for highest dive at 52.4 m (172 ft) until 1985, when Randy Dickison (fracturing his leg in the process) set a record of 174 feet 8 inches at an event in Hong Kong. In 2015, the current record for a cliff jump (not qualifying as a high dive) of 58.8 m (193 ft) was set by Laso Schaller.
