The tall whites, as described by Hall, are allegedly humanoid aliens with long limbs, pale skin and glowing blue eyes.
Unlike the little green men of pop culture, they seem more reserved — aloof but not overtly hostile. Hall claimed they had a base on Earth and were here with the government’s awareness, if not its full cooperation.
Their behavior was reportedly unpredictable. While some encounters were calm, others were stressful, especially early on when Hall was still claiming sightings without broader belief or support.
