Events
- October 29 (Black Tuesday) - In United States history, this day is generally conceded to mark the end of the Roaring '20s, a decade of nearly unbridled optimism, and the beginning of the Great Depression, a period of economic upheaval and misery. This event set the stage for Leonard McCoy's brief intervention in history that almost destroyed the future in which the Federation came to be. (TOS: "The City on the Edge of Forever")
