The dropping of the bombs on Hiroshima and Nagasaki in Japan followed soon after, but it was the first blast in what is now known as White Sands Missile Range that marked the beginning of the end of World War II.

Author Elva K. sterreich shares the stories of their experience and how their lives were transformed.
