, in 1953. He thought it would be helpful for airline accident investigators to have a recording of voices in the cockpit. While devices had been previously used to record certain flight parameters, they did not include voice recording, and were not reusable, and therefore were not practical for routine commercial flights. Warren's invention, which relied on magnetic recording media, allowed easy erasing and re-recording, which made it practical for routine line service. Warren's concept of cockpit voice recording added a new dimension to instrument data in flight recorders, and has proved extremely valuable for accident investigation. Interestingly, some accidents where the CVR played a prominent role were solved not by the crew's recorded voices, but by other sounds incidentally recorded on the CVR, which provided a vital clue to the accident cause.

Warren died 19 July 2010, at age 85, in Melbourne. He was buried in a casket bearing the label "Flight Recorder Inventor; Do Not Open".
