The story of the 10 Jesuits (German) at Hiroshima during the atomic bombing in World War II. 5 of them were within a mile of the epicenter. All 10 survived into the 1960's, despite the fact that at least the 5 Jesuits within a mile of the blast should died from radiation within 10 years after the bombing. Many scientists studied these Jesuits and marveled at the fact that they said they were protected because they lived a life as was requested by Our Lady of Fatima. The CBS Show 60 Minutes did a segment on this in the 1970s (if I remember correctly).
Josyp Tereyla, who passed away 2 years ago in March, made the fact that Chernobyl in Ukrainian meant Wormwood. The Bible has an angel of chastisement called the Angel of Wormwood, which starts with the fact that a bright flash covers the sky. On the one year anniversary of Chernobyl, an Apparition of Mary occurred in the Ukraine. Many could see this apparation. The site was a famous church that had a healing well.
Finally, in Nagasaki, Saint Maximilan Kolbe built a church such that it survived the Nuclear blast there ("Fat Man" bomb). The church was built on a side of the hill protected from the atomic blast. I guess saints just know to do certain things, and assume it is the will of God.
