History
Jackson Hardy was born in Louisiana and a war veteran who served in Belgium and Germany during World War II. After the war, he worked in military intelligence.
On July 7, 1947, Jackson participated in relocating the alien bodies from a crashed alien spaceship in New Mexico. The experience of seeing and touching actual aliens disturbed him. The day after, Jackson was selected with several soldiers into an investigation of a seemingly innocuous farm, where they found a barn painted with a symbol of a circle with a line drawn through it.
