Military

For nearly five decades, some of the United States military's most secretive operations were conducted out of a collection of nondescript buildings at the intersection of State Route 237 and Mathilda Avenue in Sunnyvale, California. The installation was known by a variety of names in its early years: Satellite Test Center, Air Force Satellite Control Facility, the "Blue Cube," and Sunnyvale Air Force Station. In July 1986, the facility was renamed Onizuka Air Force Base after Col. Ellison S. Onizuka, the first Asian American astronaut, who was killed during the space shuttle Challenger accident. The location was selected due to its proximity to Lockheed Missiles and Space Company's Sunnyvale facilities and supported early satellite reconnaissance programs such as Corona, Gambit, and Hexagon. As the nation's nucleus for satellite command and control, workers at Onizuka Air Force Base directed efforts for the National Reconnaissance Office (NRO), US military, and NASA's space shuttle program until the closure of the base in 2010.

An industrial miracle took place at the Fairfax Airport, on the shores of the Missouri River, between 1941 and 1945. A massive factory was quickly built and a large modification center was soon added. At its peak, over 24,000 greater Kansas City-area residents were employed by North American Aviation, Inc. Their goal was to build as many twin-engine B-25 Mitchell medium bombers for wartime service as possible. Their success was the construction of an unprecedented 6,608 aircraft. The B-25 Mitchell served with distinction in every theater of World War II, and significant numbers of them were provided to Allied nations. Many B-25s have been preserved, and some of them remain airworthy today. They can be seen on static display or in flight at air shows all across America.
