The Erie Canal opens, the Pony Express closes, Wyatt Earp shoots it out in Tombstone, "Baby Fae" gets a baboon heart, and the Patriot Act is signed into law, all on this day.
1881: Wyatt Earp (pictured), his brothers Virgil and Morgan, and "Doc" Holliday confront Ike Clanton's gang in a gunfight six lots down from the O.K. Corral in Tombstone, Arizona. Three members of Clanton's gang were killed and Earp's brothers were wounded in what would later become known as the "Gunfight at the O.K. Corral."
