Wingfoot Air Express Crash
The explosion took place on July 21, only days before the beginning of rioting. Some credited the disaster with raising tensions in the city. Irwin St. John Tucker, a journalist, priest, and activist, wrote about the events that July in a letter to his family. "We have been having excitement on top of alarm the past week," he explained, crediting "that blimp disaster" as the first in a series of events that left Chicago on edge in the days leading up to the race riot.
