The Hebei Power Plant Octahedron
Video and stills circulated in September 2011 showing a geometrically regular black octahedron apparently suspended near a power-plant complex in Luannan County, Hebei. At least two early online uploads are reported, but no named witness, original file, scale, range, official inquiry or verified ind
Why This Case Matters
A visually distinctive case whose value is mainly provenance/identification work: spectacular geometry does not compensate for anonymous sourcing and missing scale.
Chronology
- 9 Sep 2011 claimed sighting
- footage appears on Chinese/YouTube platforms within days
- international UFO reposts follow by mid-September
- later copies detach the image from its original upload context
The Witnesses
Evidence
The following evidence types are documented for this case:
Conventional explanations: Tethered box kite, balloon/decorative object, suspended industrial object, near-camera model or digital manipulation are viable. The static, geometrically perfect silhouette is particularly compatible with a kite/tethered object.
What Remains Unresolved
- Original Youku/native upload
- named witness
- camera metadata
- exact camera position and scale
- independence of uploaders
- any local press/power-plant record.
Key Takeaways
- Do not treat multiple reposts as multiple witnesses. Until the first-generation file and witness are recovered, this is an image-provenance case rather than evidence of extraordinary flight.
