This one tornado alone inflicted 695 fatalities, more than twice as many as the second deadliest, the Great Natchez, Mississippi Tornado of May 7, 1840. The track left by the tornado was the longest ever recorded in the world as it crossed from southeastern Missouri, through southern Illinois, then into southwestern Indiana. Although not officially rated by NOAA, it is recognized by most experts (such as Tom Grazulis and Ted Fujita) as an F5 tornado, the maximum damage rating issued on the Fujita scale.
