Grand Central Airport is a former airport in Glendale, California. Also known as Grand Central Air Terminal (GCAT), the airport was an important facility for the growing Los Angeles suburb of Glendale in the 1920s and a key element in the development of United States aviation. The terminal, located at 1310 Air Way, was built in 1928 and still exists, owned since 1997 by The Walt Disney Company as a part of its Grand Central Creative Campus (GC3). Three hangars also remain standing. The location of the single concrete 3,800-foot (1,200 m) runway has been preserved, but is now a public street as the runway was dug up and converted into Grand Central Avenue.

Howard Robard Hughes Jr. was an American aerospace engineer, business magnate, film producer, investor, philanthropist, and pilot. He was best known during his lifetime as one of the richest and most influential people in the world. He first became prominent as a film producer, and then as an important figure in the aviation industry. Later in life, he became known for his eccentric behavior and reclusive lifestyle—oddities that were caused in part by his worsening obsessive-compulsive disorder (OCD), chronic pain from a near-fatal plane crash, and increasing deafness.
