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.

Trans World Airlines (TWA) was a major airline in the United States that operated from 1930 until it was acquired by American Airlines in 2001. It was formed as Transcontinental & Western Air to operate a route from New York City to Los Angeles via St. Louis, Kansas City, and other stops, with Ford Trimotors. With American, United, and Eastern, it was one of the "Big Four" domestic airlines in the United States formed by the Spoils Conference of 1930.
