Details the progression of the Department of Civil Aviation and the crash of a DC-2 Douglas, which signalled a revolution in aviation safety. Describes with personal experiences, the rise of commercial aviation controls and support services- the Aeradio system of communications, control and beacons, air traffic control, flight checking and briefing at local and national levels through his work as an Flight Service Officer of the Department of Civil Aviation in Australia. These systems have been superseded in the 21st century, much to the author’s regret, by remote management and computer control. 276 p. : ill. (some col.), ports. ; 21 cm.
