What the official record supports
Official unresolved assessments repeatedly cite insufficient range, telemetry, or geometry as barriers to performance calculation.

Why can a precise speed be completely wrong?
Pixel motion becomes kilometers per hour only after distance, field of view, timing, and geometry are supplied.
Editorial disclosure
A resolved case is not a less interesting case. It is a chance to learn how the sky, cameras, and perception manufacture convincing mysteries.
01
30-second briefing
Start with what the primary record actually says.
Pixel motion becomes kilometers per hour only after distance, field of view, timing, and geometry are supplied.
Reading rule
An official record establishes what was documented. It does not automatically validate every interpretation or claim contained around it.
02
Evidence ledger
Trace every finding back to the record.
F-02Data limitation
Where the evidence stops
Uncertainty in one major input can dominate an otherwise exact-looking equation.
03
Conclusion boundary
Know exactly where the evidence stops.
What the primary record establishes
- Official unresolved assessments repeatedly cite insufficient range, telemetry, or geometry as barriers to performance calculation.
What it does not establish
- Uncertainty in one major input can dominate an otherwise exact-looking equation.
04
Method and limits
How this case was assembled.
This chapter begins with an appearance that can feel extraordinary, then tests the geometry, atmosphere, optics, sensor pipeline, or human behavior that may produce it.
- 01
Describe the observation before naming a candidate explanation.
- 02
Test motion, range, focus, weather, traffic, and sensor behavior as separate variables.
- 03
State which clues support an explanation and which measurements are still missing.
Methodological caution
Official records preserve provenance, observations, assessments, and testimony at different evidence levels. Later data may revise how the same record is understood.
05
Historical thread
Follow the record as it changes.
- ongoing
A calculator creates false confidence
Online reconstructions increasingly converted clips into precise performance claims using assumed distances.

Vastward interpretation
Stay curious without outrunning the evidence.
Independent editorial layer
The notes below are Vastward’s interpretation. They are not statements written by the source agency or witnesses.
Precision belongs to the assumptions as much as the result. Two decimal places do not rescue an invented range.
Publish an uncertainty interval and every major assumption beside any performance number.
- Apparent motion
- Motion seen in an image or from an observer's viewpoint that may differ from the object's true motion through space.
- Sensor artifact
- A feature introduced by optics, electronics, compression, display processing, or recording rather than by the observed scene.
