The Wingfoot Air Express was a dirigible that crashed into the Illinois Trust and Savings Building in Chicago on Monday July 21, 1919. The Type FD dirigible, owned by the Goodyear Tire and Rubber Company, was transporting people from Grant Park to the White City amusement park. One crew member, two passengers, and ten bank employees were killed in what was, up to that point, the worst dirigible disaster in United States history.
