Greenville County, South Carolina, United States
The Greenville Black Triangle
A photographer identified as C. Salvo circulated a three-frame set from 26 May 2009 showing a dark object against storm clouds near Greenville. The shape appears disc-like or manta/triangle-like depending on frame. No official record or independent witness has been recovered, and the images survive
Why This Case Matters
A highly displayable image set that demonstrates how apparent shape can shift across frames while chain-of-custody and independent corroboration remain weak.
Chronology
- 26 May 2009 three storm-cloud photographs reportedly taken
- images submitted/circulated through UFO Casebook
- archived copies preserve file sequence
- later sites label object triangle/manta/disc
The Witnesses
Evidence
The following evidence types are documented for this case:
Conventional explanations: Thrown object/model, bird or other near-camera object are serious possibilities. The changing silhouette across frames and lack of range make a small nearby object difficult to exclude.
What Remains Unresolved
- Original full-resolution files and EXIF
- complete sequence
- exact site/time
- independent witnesses
- image-forensic examination and rights.
Key Takeaways
- Spectacular shape does not compensate for single-uploader provenance and missing range. Treat as an unresolved photograph, not a confirmed structured craft.
