LONDON Human remains believed to be those of Sir Donald Campbell have been found close to the spot where his "bluebird" speedboat was recovered from a British lake two months ago, Reuters said. Divers who helped raise the wreck in March, 34 years after it flipped over and crashed in pursuit of the world water speed record, discovered the body on Sunday, police said. Campbell was 46 when he tried to break his own 276 mph (442 kph) water speed record in 1967. In his first run, he achieved a speed of 297 mph (475 kph) but on its return run the jet-powered craft hit a wave, lifted out of the water at more than 300 mph (480 mph), somersaulted and broke up.
