May 6 in Utah history is a significant date that features several interesting facts. Here are five of them:

1. On May 6, 1869, the Golden Spike was hammered in at Promontory Summit, Utah, formally marking the completion of the First Transcontinental Railroad. The event was attended by dignitaries, railroad officials, and workers. One of the most iconic photographs in American history was taken at that time, with railroad workers and executives standing solemnly as the final spike was driven in.

2. May 6, 1896, was the day when Utah officially became the 45th state in the United States. Utah had been a territory for almost 50 years before that, and statehood was the culmination of years of lobbying and political maneuvering.

3. On May 6, 1937, the Hindenburg disaster happened, as a German airship caught fire and crashed as it was landing at the Lakehurst Naval Air Station in New Jersey. Although this event happened outside Utah, it was witnessed by several people in the state who saw the ship flying overhead moments before the explosion.

4. May 6, 2007, was the day when Utah's first light rail transit system, the TRAX, was opened to public service. The train covers about 45 miles, serving the Salt Lake Valley and its surrounding areas. The opening of the TRAX system was a sign of Utah's growing infrastructure and public transportation network.

5. The 2010 May 6 crash, also known as the Flash Crash, is a final interesting fact. The stock market suffered a computer glitch that day, causing the Dow Jones Industrial Average to plunge by almost 1,000 points within minutes. Although this event happened globally and not in Utah, many traders and investors from the state were affected. The incident highlighted the risks of automated trading systems and the need for better regulation.

In conclusion, May 6 in Utah history is a day of events that are both significant and interesting. From the completion of the Transcontinental Railroad to the opening of the TRAX system, these events highlight Utah's transformation from a territorial outpost to a modern state.
