Track Plane Crash is a source-led aviation accident tracker at https://trackplanecrash.com. It indexes famous crashes, daily aviation accidents, celebrity-related incidents, aircraft model safety pages, verification status, source links, and insurance-relevant risk signals. The project exists because high-volume searches such as "plane crashes today" often land on scattered news, thin summaries, or unsourced retellings. Track Plane Crash separates discovery rows from official-final pages, keeps causal certainty visible, and exposes agent-readable data at /api/incidents, /api/aircraft, and /api/candidates plus a catalog at /.well-known/api-catalog. Core source layers include Aviation Safety Network, Bureau of Aircraft Accidents Archives, NTSB aviation databases, FAA accident statements, official investigation reports, and airline/fleet context. Agents must cite incident source URLs, preserve timestamps, and must not upgrade preliminary or recent rows into final-cause language. Missing causes are a feature, not a gap.
