It's an eerie picture of what goes through one's mind when death seems imminent.
In an interview that airs Sunday on "60 Minutes," one of the rescued Chilean miners from October admits the group contemplated suicide. According to him, there was discussion of starting an engine below ground and asphyxiating the group:
"I said to a friend, 'Well, if we are going to continue suffering, it would be better for us to all go to the refuge, start an engine and with the carbon monoxide, just let ourselves go,'" Zamora, one of the workers interviewed, told Bob Simon.
The miners, you might remember, spent over two months trapped beneath the earth.
