Dramatic
and Unusual UAP
Sightings Classifier

Describe your sighting and see how dramatically it reads compared to 20,000+ real NUFORC reports.

What does "dramatic" mean? It refers to language patterns, not whether your experience was real or significant. NUFORC editors flag reports with unusual vocabulary, vivid technical phrasing, or descriptions that deviate from typical misidentification reports. A plain account of an extraordinary event can still score low.
