Conventional airborne objects that people are bad at identifying (planes, helicopters, blimps, drones, satellites, balloons, weather phenomenon, flares, meteors)
Unintentional camera effects (lens flares, reflections, parallax, lens cover defects, digital zoom artifacts)
Hoaxes (CGI, models, intentional camera effects, and now AI)
