As the SA or "single aisle" studies (which later became the successful Airbus A320) underwent development to challenge the successful Boeing 737 and Douglas DC-9 in the single-aisle, narrow-body airliner market, Airbus turned its focus back to the wide-body aircraft market.
Cando os estudos para un avión de corredor único (que posteriormente se converterían no exitoso Airbus A320) comezaron a desafiar aos Boeing 737 e Douglas DC-9 no mercado de avións de fuselaxe estreita, Airbus volveu a centrarse no mercado dos avións de fuselaxe ancha.
