Donald Campbell
Donald Malcolm Campbell, (23 March 19214 January 1967) was a British speed record breaker who broke eight absolute world speed records on water and on land in the 1950s and 1960s. He remains the only person to set both world land and water speed records in the same year (1964). He died during a water speed record attempt at Coniston Water in the Lake District, England.
Bluebird K7
Donald Campbell began his record-breaking career in 1949 following the death of his father, Sir Malcolm Campbell. Initially, he had been using his father's 1939-built Rolls-Royce 'R' type powered propeller-driven hydroplane "Blue Bird K4" for his attempts, but he met with little success and suffered a number of frustrating setbacks. In 1951, "K4", which had been modified to a prop-rider configuration to increase its performance potential, was destroyed after suffering a structural failure, when its V-drive gearbox sheared its mountings, and punched through the floor of the hull.
