[edit] History of FDR

I think one of the first (maybe the first) FDR was an Finnish "Mata Hara" invented during early 40's.

I'm interested to know about failure rates in FDR and CVRs (i.e. from excessive damage); I'm also interested in finding out how regularly the FDRs and CVRs are not found.

[edit] Developer of the "black box" from University of Minnesota

James Ryan was born on November 27, 1903 in LeClaire, Iowa. In 1925 he received his B.S. in mechanical engineering from the University of Iowa, and in 1929, he received his M.S. in mechanical engineering from the University of Pittsburgh, doing his graduate work at Stanford University. Ryan came to the University of Minnesota as an assistant professor in mechanical engineering in 1931, being promoted to associate professor in 1940, and becoming a full professor in 1950.

Concerned about automobile safety, in 1949 Ryan began crashing cars into walls while his students observed, to complete his own testing in auto safety experiments. As a result, he invented the retractable seat belt, which he patented in 1963. Although nicknamed "Crash" Ryan, he was never injured in the experiments, and federal government researchers frequently consulted him on research. He also invented the flight data recorder, or "black box" patented in 1963, and now required on all commercial airlines. He conducted experiments under grants from the Office of Naval research, the Naval Medical Research Institute, the National Research Council, the United States Air Force, and the United States Public Health Service.

In 1963, Ryan retired because of a rheumatic heart condition. He passed away on May 31, 1973 at the age of 69. —The preceding unsigned comment was added by 128.101.7.29 (talk) 19:38, 9 March 2007 (UTC).
