Math chose these. Not us.
Each entry was flagged by the statistical model after the baseline period. Each row is cryptographically hashed, timestamped, and chained. We didn't pick them. The deviation from normal did.

Detections inside the height-velocity hazard envelope
Every row below is a flight detected at or under 500 ft while airborne — the altitude band where a helicopter has no time to autorotate to a survivable landing if the engine fails. Reference: FAA AC 90-87C (Helicopter Height-Velocity Diagram). Altitude here is reported barometric; negative and zero-altitude transponder anomalies are excluded.
