FBI-UAP-D043 / DOW-UAP-D176 — Observation of a Dark Triangular Aerial Object, Western United States 2026

The officially released sources FBI-UAP-D043, DOW-UAP-D176 document two corresponding but not mutually explicit documents about a reported dark, nonreflective triangular form. The sources relay a uniform thermal signature without visible exhaust, reported absence of audible sound, a vertical ascent, and later rapid horizontal movement as witness accounts. Redactions, estimated dimensions and duration, and absent instrumented speed, raw imagery, telemetry, and acoustic data limit the account. The delta-wing-drone similarity is not an identification; the documents establish neither manufacturer, operator, propulsion, NHI, nor exotic technology. D176 and FBI-UAP-D043 appear together only on this one page.
