Grand Central Airport was a municipal airport developed from 1923 which became the largest employer in Glendale for many years, and contributed to the development of aviation in the United States in many important ways. The main terminal building still stands and includes both Art Deco and Spanish-style architectural elements. The facility was the first official terminal for the Los Angeles area, as well as the departure point for the first commercial west-to-east transcontinental flight flown by Charles Lindbergh. During World War II, the Grand Central Air Terminal building was camouflaged to protect it from enemy targeting. It was closed down in 1959, and made way for the Grand Central Business Centre, an industrial park.
