In a hospital far from home, Tina Wilson is still pulling pieces of glass and gravel from her hair. She says she will never drive a bus again. She does not remember the moments after a tire blew out on her charter bus this month, nearly tipping it and the 56 University of South Carolina students on board. She does not remember using all her strength to steer the bus back to standing, only to be thrown through the windshield and across Mississippi’s busy Interstate 10.
