January 30 in Washington history has been a significant day for several reasons. Here are five interesting facts about this day:

1. The Boeing 747 made its first commercial flight on January 30, 1970. This iconic aircraft was developed by Boeing in the late 1960s to meet the demand for long-haul air travel. The first commercial flight was operated by Pan American World Airways and flew from New York's John F. Kennedy International Airport to London's Heathrow Airport.

2. On January 30, 1933, Adolf Hitler became Chancellor of Germany. This event had a profound impact on the world and led to the rise of the Nazi regime and the atrocities committed during World War II. The United States was one of several countries that eventually went to war against Nazi Germany.

3. The Space Shuttle Challenger disaster occurred on January 30, 1986. This tragedy took place just 73 seconds after liftoff, when an O-ring seal failed on one of the solid rocket boosters. All seven crew members were killed in the disaster, including Christa McAuliffe, who was set to become the first private citizen in space.

4. Seattle's historic Union Station was opened on January 30, 1911. This impressive Beaux-Arts building served as the city's primary rail terminal for decades, with trains arriving and departing from its ornate halls. Today, the building is home to several offices and event spaces.

5. On January 30, 1964, the Washington State Legislature approved the creation of the Seattle Opera. This institution has since become one of the nation's premier opera companies, staging both classic and contemporary works. The 2021 season was disrupted due to the COVID-19 pandemic, but the Seattle Opera has continued to perform virtually and plans to return to in-person shows when it is safe to do so.
