The creation of the National Transportation Safety Board was the first independent agency charged with investigating the safety of various transportation systems, from highways and pipelines to railroads and airplanes. Since 1967, the NTSB has investigated more than 130,000 accidents.
These investigations are vital since they help establish “the who, what, where, when, how and [perhaps] why behind an incident.” After the facts are determined, policymakers can back up, and often have backed up, NTSB recommendations with new regulations. Failing that, it is common for air carriers, for example, to voluntarily implement changes it suggests. A similar approach could help improve the internet, a new technology that, like airplanes, is tying the world closer together even as it threatens our shared security.
