Dear Mr. Walker,
In 1997, as a result of recommendations from the White House Commission on Aviation Safety and Security  the National Aeronautics and Space Administration (NASA) initiated a program to track aviation safety trends quantitatively; monitor the effects of technological and procedural changes to the National Aviation System and contribute to the development of a quantitative, data-driven basis for safety decisions. Most of the previous safety-related data bases were based on self-reports and therefore not statistically reliable to determine trends or the effects of changes to the aviation safety system. NASA was selected to initiate this effort because of its success in operating the self-reporting Aviation Safety Reporting System.
