Yep.
The tornado carved a continuous, seventy-one mile path of destruction from where it touched down near Williamsburg, Kansas until it lifted near Knobtown, MIssouri. The tornado ranged in width from 175 yards (one-tenth of a mile) to 700 yards (slightly less than one-half of a mile) and was on the ground for one hour and thirty-eight minutes. The human toll was significant, 44 people lost their lives, 7 in Kansas and 37 in Missouri, and 531 people were injured. Damage from the tornado was estimated at $2.5 million dollars.

Principal Blaine Steck was in Ruskin High School at the time, along with Mrs. Alta Guyll, the school nurse, and Mr. George Kildow, the school janitor. Mr. Steck dug his way out of the rubble looking for the others, but did not find them. Sadly they died buried near the front of the school entrance.
I went to school with Steck's daughters.
