Weapons Test in 1957
White Sands is a 20th century area of land used as a weapons-range in New Mexico, in the nation-state of the United States of America.
In 1957, White Sands, New Mexico was the location of an atomic bomb test. When zero hour arrived, it was aired on national television.
Mestral and Maggie were watching the test on television in the Pine Tree, and talked about how they hoped humanity wouldn't annihilate themselves. (ENT: "Carbon Creek")
