On Paper Wings is the story of four Japanese women who worked on balloon bombs, the families of those killed in the U.S., and the man whose actions brought them all together forty years after WWII, and the balloon bomb project.

During WWII, the Japanese military developed a new weapon intended to strike directly at the American continent – the balloon bomb. Thousands of hydrogen-filled balloons were attached to bombs and then launched into the jet stream to drift toward North America.

When six civilians found a balloon bomb in Southern Oregon, the device exploded. They became the only people killed on the continental U.S. as the result of enemy action during WWII.

This is the story of four Japanese women who worked on balloon bombs, the families of those killed in Oregon, and the Japanese American man whose actions brought them all together forty years after WWII, and the balloon bomb project.
