East Marginal Way South beside Boeing Field, Seattle, Washington, United States
The Seattle Triangle (1993)
Seattle writer and illustrator Gary Val Tenuta says that on a Sunday night in November 1993 he stopped beside Boeing Field and watched three steady red lights resolve into a huge black triangular silhouette moving slowly and silently overhead. Tenuta later signed a sworn affidavit used in CAUS litig
Why This Case Matters
A named, consistent black-triangle witness who committed his account to a sworn affidavit, but whose striking size/altitude claims remain unanchored by independent data.
Chronology
- Nov 1993 ~21:30 claimed sighting beside Boeing Field
- Tenuta stops vehicle and watches object pass east-to-west
- account later published under his name
- sworn affidavit incorporated into CAUS triangle litigation
The Witnesses
Evidence
The following evidence types are documented for this case:
Conventional explanations: Conventional aircraft/formation, airship, or perceptual completion of a dark triangle between three lights remain viable; size, altitude and silence estimates depend entirely on visual judgment.
What Remains Unresolved
- Exact date
- original affidavit/case filing text specific to Tenuta
- FAA/tower records
- independent witnesses
- weather/cloud-base reconstruction.
Key Takeaways
- The affidavit strengthens accountability, not physical corroboration. Present this as a committed single-witness report rather than evidence that a football-field craft crossed controlled airspace.
