NOTES: Includes operators with a U.S. Department of Transportation, Federal Aviation Administration operating certificate engaged in scheduled passenger or public charter passenger operations and airports at which these operations are conducted.  Beginning in 1996, the Office of Civil Aviation Security Policy and Planning stopped keeping records of bomb threats received due to inconsistent reporting. The reporting of other dangerous articles was discontinued in 1992 and reporting of explosive/incendiary devices was discontinued in 1994 for the same reasons.",,,,,,,,,,,,,,
