What this example establishes

The spectrogram comes from the supplied recording. Cyan tracks are saved automatic detections, not a fresh scan or verified aircraft matches. The first group is consistent with harmonic orders 2, 5 and 7 of one source. The optional dashed lines are independent ideal constant-speed, constant-pitch fits.

No historical aircraft tracks, UTC synchronization, observer position, or geographic solution have been established. The camera moves during parts of the full recording; a stationary microphone is not assumed. Video and curves share the source recording timeline, without an independently measured broadcast audio/video offset.
