On the 25th of October, 1938, Australia's worst pre-war aviation disaster occurred on the western face of Mount Dandenong. The Douglas DC-2 Kyeema, operated by Australian National Airways (ANA), was en route from Adelaide to Melbourne when it overshot Essendon Airport by some 20 miles as it descended through thick cloud, crashing into the side of Mount Dandenong, killing all 18 occupants. The accident, which still ranks as the sixth worst in Australia's commercial aviation history, electrified the nation. The subsequent inquiry found that an inadequate radio system and inexplicable, gross navigational errors by the experienced crew caused the disaster. The findings triggered the beginning of air traffic control as we now know it in Australia, and the eventual founding of the Department of Civil Aviation.
