This is the story told by the late Phil Schneider, a geologist and engineer who said he had level-1 security clearance in secret government projects. He helped build underground military bases and worked at the famed Area 51 base.
Schneider showed a picture of Thor during a lecture at the 1995 Preparedness Expo. The photo was taken in 1943. Schneider said the alien had been working for the U.S. military since 1937.
Thor left Earth on the morning of March 16, 1960, according to Dr. Stranges. He left in a spaceship from Alexandria, Va.
