Potez 840

The Potez 840 that resembled a Viscount crossed with a Jetsteram first flew on 29 April 1961. Powered by four 440shp (328 kW) Turboméca Astazou II It had a crew of three and a cabin for 18 passengers. A second aircraft flew in June 1962 and had more powerful 600shp (447 kW) Turboméca Astazou XII engines.
It was planned to build a batch of 25 aircraft for Chicago based Turbo Flight Inc. but only two more prototype aircraft were built, one for static testing. The next two aircraft were designated the Potez 841 powered by 550shp (417 kW) Pratt & Whitney Canada PT6A-6 turboprops. Two more modified Aztazou-powered aircraft Potez 842 were produced, one in 1965 and one in 1967. A total of 8 the 840srs were built and it never had a chance of being the DC-3 replacement!

Wilson Global Explorer

The Wilson Global Explorer is an American-built amphibious aircraft of the early 1990s which has been utilised to assist the exploration of remote areas. The high-wing twin-engine aircraft was designed and constructed by Dean W. Wilson to the order of the explorer Hubert de Chevigny and the aircraft first flew in April 1991. A second aircraft was constructed later.

The Global Explorer has an unusually deep and wide fuselage design with many inserted glazed areas and accommodation at the rear for sleeping and other purposes. For added strength, the high-set wings are each supported by brace structures from the side fuselage and from the lower sponsons. The nose gear retracts forward of the hull and acts as a bumper for operations off water. The main wheels can be removed and the fixed side sponsons assist flotation and manoeuvring on water. Various Lycoming engines of between 200 hp and 300 hp have been fitted, depending on the expected altitude to be reached during planned operations
The Global Explorer has been used by Hubert de Chevigny, with the name "L'Avion" on its nose, in the exploration and filming of a wide variety of locations including Australia's Great Barrier Reef, Argentina's Tierra del Fuego and Bolivia. It can be readily stripped down and shipped by sea to required locations and can carry and accommodate seven persons overnight.
