NASA has today released a series of images along with a video following Monday’s devastating thunderstorms that produced an F-4 tornado¬†(winds between 166 and 200 miles per hour) that touched down in Moore, Oklahoma. As far as we can tell, there are only two people on record that claim to have been in the center of a tornado and lived. A tornado is a violent rotating column of air descending from a thunderstorm to the ground. Tornadoes are formed several thousand feet above the earth's surface inside of a severe rotating thunderstorm. Tornadoes form under particular weather conditions in which three very different types of air come together in a certain way.

This rotation is responsible for severe weather events such as large hail, heavy showers and tornadoes.
In the United States, the vast majority of tornadoes occur in the Tornado Alley but they can occur nearly anywhere in North America. Most tornadoes travel from the southwest to the northeast direction with an average speed of 30 mph. Temperature and moisture differences between the surface and the upper levels create what we call instability, which is the most necessary ingredient for tornado formation. He spotted an umbrella-shaped cloud in the near distance and had a feeling that a tornado might develop.

The tornado then passed, skipping over his house and smashing the home of his neighbor.The second account from Roy Hall does nothing to disprove Keller's story.
