Some Americans took these suggestions very seriously.
Among them was businessman Girard Brown (Jerry) Henderson.
Henderson constructed a luxurious fallout shelter at his home in Las Vegas, 26 feet underground.
From the outside and on the surface, its a modest two-story suburban house.
The subterranean bomb shelter is a two-bedroom house with a kitchen and bathrooms and additional rooms for guests.
To mimic lighting condition at different times of the day, lights are dimmed or brightened.
At night stars on the ceiling are turned on.
The shelter was built in 1978, but it wasnt Hendersons first underground home.
His first home was near Boulder, Colorado.
Henderson continued to live at his underground house until his death in 1983.
After his wife passed away in 1989, the house was passed on to a distant relative.
Its unclear what the group plans to do with the house.
