NOTES: 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/other dangerous articles was discontinued in 1992 and reporting of explosive/incendiary devices was discontinued in 1994 for the same reasons.
