Sydney, Jul 21: The inventor of Black box, David Warren, died at the age of 85 in Australia on Wednesday, Jul 21.

Dr David Warren was a researcher in the Aeronautical Research Laboratories in Melbourne, Australia. He invented the Black Box, flight-data recorder, in 1953 and in production by 1957.

He was the first person to conceive of the idea of recording the flight crew's conversation on an airplane and of protecting that recording in the event of a crash or fire.

The purpose of the Black Box was to help identify the reasons for a plane crash, by recording any clues in the flight crew's conversation.

The first Black Boxes were painted bright red or orange to make them easier to find after a crash. In 1960, Australia became the first country to make flight recorders mandatory in aircraft.

Modern black boxes record up to 300 factors of flight including airspeed and altitude, heading and vertical acceleration, aircraft pitch, cockpit conversations and radio communications.
