Nieuport-Delage NiD 30

The Nieuport-Delage NiD 30 was a French airliner that entered service in 1920. It was a reverse-stagger biplane with an enclosed cabin seating four passengers and an open cockpit for the pilot, with provision for a wireless transmitter, receiver and operator, and it was powered by a single Sunbeam Matabele engine of 260 kilowatts. Compagnie generale transaerienne operated seven examples on its Paris to London route with twice-daily return services. After one was lost in thick fog over the Channel on 27 April 1920 the remaining aircraft were fitted with an early audible guidance system, but after a number of further accidents they were withdrawn from service in February 1921. A larger six-passenger variant with longer overhung top wings, the NiD 30T2, was shown at the 1921 Salon de l Aeronautique but was not produced.
