The Kawasaki Ki-56 (Japanese: 一式貨物輸送機, Type 1 Freight Transport) was a Japanese two-engine light transport aircraft used during World War II. It was known to the Allies by the reporting name "Thalia". 121 were built between 1940 and 1943. The Kawasaki Ki-56 was derived from the Lockheed Model 14 Super Electra aircraft that the Kawasaki Kokuki Kogyo Kabushiki Kaisha (The Kawasaki Aircraft Engineering Company Limited) had built under licence. In September 1939 Kawasaki was asked by the Koku Hombu to design an improved version as Ki-56. A number was also built by Tachikawa Hikoki K.K. The Japanese invasion of Sumatra in the Dutch East Indies campaign began with a paratroop drop from Ki-56 transports on Airfield P1 and the oil refineries near Palembang. Royal Air Force Hawker Hurricane fighters flying from P1 to locate the Japanese invasion fleet passed the incoming Ki-56s, but thought them to be friendly Lockheed Hudsons (also developed from the Lockheed Model 14) returning from a raid. The defending anti-aircraft gunners at P1 were equally fooled, until the parachutes began to open. Once the AA guns opened fire one transport was shot down, another force-landed, and others veered off course, but the paratroop drop was effective and the airfield and oil installations were overrun.

The Emigh A-2 Trojan was an American single-engined cabin cantilever monoplane designed and built by the Emigh Trojan Aircraft Company of Douglas, Arizona. The A-2 had side-by-side seating in an enclosed cabin for a pilot and passenger. Of all metal construction it had a fixed tricycle landing gear and was powered by a Continental A90 flat-four piston engine. Many major components of the aircraft were designed to be interchangeable to simplify and lower manufacturing costs. The vertical and horizontal stabilizers where interchange able as well as the rudder and elevators. A symmetrical section of the wing was interchangeable and the upper and lower fuselage skins were also identical. A total of 58 Trojans had been completed when production ceased in 1950.

The Helio Twin Courier is a twin-engined version of the Helio Courier, with only seven examples being produced. Known by Helio as the model H-500 this STOL aircraft mounted twin Lycoming engines on top of the high-set wing, close to the fuselage. With the engines mounted in this manner, lateral and over-the-nose visibility were much improved while the propellers were kept clear of cabin doors and away from possible debris damage during rough field operations. This was a tail-wheel design, so the vertical component of propeller thrust assisted STOL take-off performance from rough fields. In 1967 or 68, work was started on a redesign of the Twin Courier in a tricycle-gear configuration for the commercial market, since many firms which desired STOL capability had regulations which required multi-engine aircraft. The company ran out of money and the project was terminated. The aircraft structure of the Helio Stallion, a single-engine turboprop version of the more successful Helio Courier, was based on the design of the Twin Courier. The Twin Courier could seat six and first flew in April 1960, being awarded FAA certification on June 11, 1963. (The Twin Courier met FAA requirements marginally and was certificated to meet immediate needs for service in Vietnam, on the understanding that the design would not be marketed commercially. Thus, the redesign mentioned above.) Only seven examples were built, these receiving the United States Armed Forces designation U-5A. One was reported to have been evaluated by US Army Special Forces. Furthermore, fully automatic full-span, leading-edge slats were fitted along with high-lift flaps.

The Stits SA-11A Playmate is a homebuilt aircraft design that features a rapid wing-folding mechanism for trailering or storage. The SA-11A is a single engine, side-by-side configuration seating, tricycle gear, strut-braced, low wing monoplane. The fuselage is welded steel tubing with aircraft fabric covering. The wings have a quick release mechanism that allows them to fold and lock alongside the fuselage in 15–30 seconds. Safety mechanisms were put in place so pilots could visually inspect that the wings were locked in place. A small sideways seat in the rear can accommodate 150 lb (68 kg) of luggage or a light passenger. The prototype was donated by Ray Stits in 1969 to the EAA AirVenture Museum in Oshkosh, Wisconsin. Its engine went into the Stits SA-9A "Skycoupe" prototype for testing and development.

The Hovey Whing Ding is an extremely minimalist American ultralight aircraft that was designed by Bob Hovey of Saugus, California, first flying in 1971. The aircraft is supplied in the form of plans for amateur construction by the Vintage Ultralight and Lightplane Association of Marietta, Georgia. Hovey set out to create the lightest aircraft to carry a person ever to fly, with the resulting design being a biplane, with a plywood box filled with Polyurethane foam serving as the fuselage, supporting the pilot's seat. The aircraft features a conventional fabric-covered empennage carried at the end of a short tailboom made of aluminum tube. The horizontal stabilizer is made from reinforced cardboard. Early versions used wing warping for roll control, while later models used full-span ailerons. The specified pusher configuration powerplant is a McCulloch chainsaw engine turning a hand-carved wooden propeller via a chain drive. The first prototype had a monowheel undercarriage, with skids under the wingtips, but this was soon changed to twin mainwheels carried on a spring-type strut. With no brakes to stop the aircraft after landing, pilots were supposed to press their heels against the mainwheels. The Whing Ding was designed long before the US FAR 103 Ultralight Vehicles regulations were introduced, but it fully conforms to the rules. The Whing Ding helped generate interest in ultralight aircraft and lead to the ultralight boom of the late 1970s and 1980s. Hovey conceived of the aircraft as an experimental project and not as a form of transportation. Due to its unreliable powerplant he intended it to only be flown over open areas where a safe landing could be carried out at any time. The plans were complex to follow and were not intended to make construction easy. Construction time typically is about 400 hours. The Whing Ding was marketed as plans, and sold extremely well - by 1979, over 6,000 sets had been purchased. In 2011 the plans were still available, and at no cost. Depending on the density altitude and the weight of the pilot, some builders discovered that the aircraft was under powered and suffered from too small a wing area to climb out of ground effect. Variants Whing Ding Initial version Whing Ding II Improved version, incorporating a higher seat to prevent pilots dragging their feet on the ground to stop the aircraft, which resulting in broken bones in some cases.

The Vickers Vulcan was a British single-engine biplane airliner of the 1920s built by Vickers Limited at Brooklands Aerodrome, Surrey. It carried eight passengers and a pilot. The Vickers Vulcan was designed by Rex Pierson of Vickers. It first flew in April 1922 at the hands of chief test pilot, S. Cockerell, at Brooklands Aerodrome in Surrey, UK. The Vulcan was based on a civil version of the Vimy bomber, but featured many changes, including a much larger, taller fuselage and one, instead of two, Rolls-Royce Eagle VIII engines, the intention being low operating costs. The shape of its fuselage, as well as its flying characteristics, earned it the nickname "Flying Pig". The first delivery took place in August 1922, to Instone Air Line Ltd. Other operators included Imperial Airways and Qantas (however, the latter returned the aircraft as their performance was too poor for the company's needs). The last Vulcan flying was a Type 74 with Imperial Airways. It crashed in July 1928 while on a test flight from Croydon Airport. Variants Type 61 - first production version, five built. Type 63 - cargo version based on the Type 61, one built Type 68 - proposed colonial variant with an Eagle VIII engine, not built. Type 74 - upgraded to 450 hp Napier Lion engine, two built (Specifications below) Type 86 - proposed all-metal variant with an Eagle VIII engine, not built.

The Ayres Thrush, formerly the Snow S-2, Aero Commander Ag Commander, and Rockwell Thrush Commander, is an American agricultural aircraft produced by Ayres Corporation and more recently by Thrush Aircraft. It is one of the most successful and long-lived agricultural application aircraft types in the world, with almost 2,000 sold since the first example flew 68 years ago. Typical of agricultural aircraft, it is a single-seat monoplane of conventional taildragger configuration. Originally powered by a radial piston engine, most examples produced since the 1980s have been turboprop-powered. The Thrush, designed by Leland Snow, first flew in 1956 and before long was being produced in series as the S-2 by the company he founded, Snow Aeronautical. In 1965, the corporation and all of its assets were purchased by the Aero Commander division of Rockwell, which put it into production alongside the CallAir A-9 that it had also acquired, branding both unrelated (though similar) machines as "Ag Commanders". When Rockwell dropped the Aero Commander brand, the S-2 was renamed the "Thrush Commander". In 1977, Rockwell sold off the production rights to the aircraft and the production facility at Albany, Georgia, which were purchased by Ayres Corporation, a firm which had been built on retro-fitting turboprop engines to Thrush Commanders. On June 30, 2003, Ayres' assets were purchased by Thrush Aircraft, the current producer of the aircraft. The S-2 and its several variants have been purchased by agricultural spraying operators in many countries. Large numbers are operated in the United States and Australia, while other countries using the type include Costa Rica, France, Guyana, Iran, Israel, Jamaica, the Netherlands and the United Kingdom. Ayres developed a special anti-narcotics crop-spraying version of the Turbo-Thrush for the United States Department of State. This version, known as the Narcotics Eradication Delivery System (NEDS) featured an armored cockpit and engine to protect against hostile ground fire. Nine were sold to the Department of State between 1983 and 1985. Ayres also attempted to market a militarized version as the Ayres Vigilante, intended for the Close Air Support role, but this failed to attract customers. IOMAX USA of North Carolina, which had previously modified Air Tractor AT-802 agricultural aircraft as reconnaissance/attack aircraft, has developed the Archangel attack aircraft modeled on the S-2R-660. The United Arab Emirates has ordered 24 Archangels, with delivery from June 2015. Two Thrush 510Gs were modified to perform a counter-insurgency role by the Austrian company Airborne Technologies at the direction of Erik Prince, the former head of Blackwater, but in the absence of an export license the aircraft have not been used operationally.

In 2011, Airbus redesigned the A350-1000 with higher weights and a more powerful engine variant to provide more range for trans-Pacific operations. This boosted its appeal to Cathay Pacific and Singapore Airlines, who were committed to purchase 20 Boeing 777-9s, and to United Airlines, which was considering Boeing 777-300ERs to replace its 747-400s. Emirates was disappointed with the changes and cancelled its order for 50 A350-900s and 20 A350-1000s, instead of changing the whole order to the larger variant. Assembly of the first fuselage major components started in September 2015. In February 2016, final assembly started at the A350 Final Assembly Line in Toulouse. Three flight test aircraft were planned, with entry into service scheduled for mid-2017. The first aircraft completed its body join on 15 April 2016. Its maiden flight took place on 24 November 2016.

The Stearman-Hammond Y-1 was a 1930s American utility monoplane built by the Stearman-Hammond Aircraft Corporation and evaluated by the United States Navy and the British Royal Air Force. In the early 1930s Dean Hammond designed the Hammond Model Y, a low-wing monoplane twin-boom pusher monoplane. Hammond cooperated with the aircraft designer Lloyd Stearman to develop the type for production. They formed the Stearman-Hammond Aircraft Corporation in 1936 to build the aircraft as the Stearman-Hammond Y-1. The first aircraft was powered by a 125 hp (93 kW) Menasco C-4 piston engine driving a pusher propeller. The performance was not impressive so it was re-engined with a 150 hp (112 kW) Menasco C-4S and re-named the Y-1S. Although designed to be easy to fly the high price meant only 20 aircraft were produced. The aircraft had no rudder as such, the tailplane fins being adjustable but fixed in flight. Turning was by differential aileron and elevator alone. In 1934 the Bureau of Air Commerce held a competition for a safe and practical $700 aircraft. In 1936 the winner of the competition was the Stearman-Hammond Y-1, incorporating many of the safety features of the Ercoupe W-1. Two other winners were the Waterman Aeroplane and a roadable autogyro from the Autogiro Company of America, the AC-35. Twenty-five examples were ordered by the bureau at a price of $3,190 each. The first delivery was considered unacceptable in finish, prompting the production of the re-engineered Y-S model. Two Y-1S, serial numbers 0908 and 0909,were used for radio controlled development trials by the United States Navy as the JH-1. A successful unmanned radio-controlled flight was made with a JH-1 drone on 23 December 1937 at the Coast Guard Air Station, Cape May, N.J. Take-off and landing was controlled via a land based radio set; for flight maneuvers, control was shifted to an airborne TG-2. KLM purchased a Y-1 (PH-APY) for use in training their pilots in tricycle undercarriage. The Royal Air Force also evaluated a former KLM Y-1S in the 1940s.
