Astronaut Neil Armstrong developed a fascination with flight at an early age and earned his student pilot’s license when he was 16. In 1947, Armstrong began his studies in aeronautical engineering at Purdue University on a U.S. Navy scholarship.
His studies, however, were interrupted in 1949 when he was called to serve in the Korean War. A U.S. Navy pilot, Armstrong flew 78 combat missions during this military conflict. He left the service in 1952, and returned to college. A few years later, Armstrong joined the National Advisory Committee for Aeronautics (NACA), which later became the National Aeronautics and Space Administration (NASA). For this government agency he worked in a number of different capacities, including serving as a test pilot and an engineer. He tested many high-speed aircraft, including the X-15, which could reach a top speed of 4,000 miles per hour.
