1970 An F5 tornado struck the city of Lubbock, TX killing 26 persons, injuring more than 1500 others, and causing $135 million in damage. It was the most destructive tornado ever up until that time. The twister hit a 30-story building in downtown Lubbock, twisting the structure and blowing out all the windows, but leaving it intact. The building still stands today.
