This is a pretty rare photo of the 1946 Baker test from Operation Crossroads.

People in Leedey, Oklahoma (with less than 900 in population) experienced the rare event to see a tornado travel towards them in the late hours of May 31, 1947. People had 30 minutes of advanced notice that tornado was coming.
Meanwhile, Jack Sapp was working as a telephone lineman and was one of the first people to see the oncoming tornado. Sapp was able to sound the town's fire siren and through a loudspeaker, was able to command the town and surrounding area seek shelter.
In 5 minutes, 75% of the people in the town had evacuated to the shelter.
After the tornado obliterated the town of Leedey in under 10 minutes, a local resident stated that the noise the tornado made was comparable to a dozen freight trains traveling in unison. Not only did the tornado completely destroy buildings and rip apart a church, it launched cars several hundred feet away and twisted a steel water tower out of shape.
When Reverend Elmer Shackleford left the storm cellar in his house, he stated that the only remnant of the church was a pile of lumber.
Approximately two thirds of the town of Leedey was destroyed and the church, the main area of town and almost all of the 100 homes left in Leedey were significantly damaged or completely destroyed.
The town of Leedey lost six of its residents due to the tornado and the town's mayor, Floyd Gale, stated that Sapp's quick thinking and actions saved at least 200 people in Leedey.
There were a number of unusual occurrences that happened during the tornado, like cars, a bell, and a couple of chimneys travelling in different directions.
