The first aircraft specifically ordered for Imperial Airways was the Armstrong Whitworth Argosy. This three-engined airliner first appeared at Hendon in July 1926 and started European services reaching Paris in two and a half hours from Croydon. Later models served the Indian routes before being replaced by the HP42.
