The Nieuport-Delage NiD 30 was a French airliner which entered service in 1920.[1][2] It was a reverse-stagger biplane design with an enclosed cabin that seated four passengers and an open cockpit for the pilot. Provision was also made for a wireless transmitter, receiver, and operator.[3] Seven examples were operated by Compagnie générale transaérienne on its Paris–London route on twice-daily return services.[2][4]
Following the loss of one of these machines[5] in thick fog over the Channel on 27 April 1920, the remaining NiD-30s were fitted with an early audible guidance system.[2] However, after a number of further accidents, these were withdrawn from service in February 1921.[4]
A larger, six-passenger variant with longer overhung top wings was developed as the NiD 30T2 and displayed at the 1921 Salon de l'Aéronautique,[6] but this was not produced.[2][4]
