Who invented black box used in aeroplanes?
When a number of the worlds first jetpowered airliners, the famous De Havilland DH-106 Comet, began inexplicably falling out of the sky in 1953, it looked like the age of commercial jet travel would stall before it even took off. Engineers and scientists pondered on what lay behind the crashes, but there were few clues and no witnesses or survivors.
In Australia, Dr David Warren, a chemist focusing on aircraft fuel, was asked to look into the mystery. Based at the Aeronautical Research Laboratories in Melbourne, Warrens role was to consider whether fuel explosion could be responsible. However, his interest in plane crashes extended beyond chemistry, for he had lost his father in an unexplained plane crash when he was only nine.!!
Warren, who died Monday, came up with the idea for the cockpit voice recorder after investigating the crash of the world's first commercial jet airliner, the Comet, in 1953, the Department of Defence said in a statement. He thought it would be helpful for airline accident investigators to have a recording of voices in the cockpit.
He designed and constructed a black box prototype in 1956, but it took several years before officials understood just how valuable the device could be and began installing them in commercial airlines worldwide.
