UFO
A classic term for an airborne object that could not be identified at the time it was seen.
UFO means Unidentified Flying Object. Historically it meant “not yet identified,” not “proven alien craft.”
Many researchers now use UAP alongside or instead of UFO. Both appear in community conversation; clear observation notes matter more than the acronym chosen.
