1. South Dakota became a state on November 2, 1889. However, on April 29, 1936, the state saw one of the worst natural disasters in its history. A massive dust storm swept through the state, causing significant damage to crops and leading to the decision to establish the Civilian Conservation Corps (CCC) in South Dakota to address the need for soil conservation.

2. April 29, 1945, is a significant date in South Dakota history because it marked the end of the World War II for many South Dakotans. On this day, German forces in Italy officially surrendered, effectively ending the war for the American troops serving there.

3. On April 29, 1980, the South Dakota State Capitol building in Pierre was added to the National Register of Historic Places. The Capitol, which was completed in 1910, is a stunning example of the Beaux-Arts style of architecture and is still in use today as the seat of South Dakota's government.

4. April 29, 1982, was an exciting day for aviation enthusiasts in South Dakota. On this day, a team of pilots from the South Dakota Air National Guard became the first group to fly a B-1B Lancer bomber across the Atlantic Ocean, delivering the shiny new aircraft to its base in South Dakota.

5. Finally, April 29, 1998, is a date that will forever be etched in South Dakota's history as the day a massive tornado struck in the small town of Spencer. The tornado, which was rated an F4 on the Fujita scale, destroyed or damaged nearly every building in the town and claimed six lives. In the aftermath of the storm, the people of Spencer rallied together to rebuild their community, and today, the town stands as a testament to the strength and resilience of South Dakotans in the face of adversity.
