just as students were getting on the buses to go home. Just before 4 p.m. CST, the tornado reached the school. Twelve buses, already filled with elementary- and middle-school students, were tossed about. Several of the students were tossed into adjacent fields and killed. A bus driver was killed as well. Shortly after the passing of the tornado, faculty and some of the stronger students used the fireproof doors of the high school as stretchers to carry the injured into the cafeteria, the severely injured into the library, and the dead into the gymnasium. Four hundred cars (three hundred new cars and 100 employee cars) were destroyed at the Chrysler plant in town. A school bus driving south of Harvard was thrown into power lines and torn in half. The driver and students survived by sheltering in a ditch.
