The Boeing 707 is a long-range narrow-body airliner produced by Boeing Commercial Airplanes, its first jetliner. Developed from the Boeing 367-80, a prototype first flown in 1954, the initial 707-120 first flew on December 20, 1957. Pan American World Airways began regular 707 service on October 26, 1958, and it was built until 1979. A quadjet, the 707 has a swept wing with podded engines. Its larger fuselage cross-section allowed six-abreast economy seating, retained in the later 720, 727, 737, and 757.
The Curtiss C-46 Commando is a twin-engine transport aircraft derived from the Curtiss CW-20 pressurised high-altitude airliner design. Early press reports used the name 'Condor III' but the Commando name was in use by early 1942 in company publicity. It was used as a military transport during World War II by the United States Army Air Forces and also the U.S. Navy/Marine Corps, which used the designation R5C. The C-46 served in a similar role to its Douglas-built counterpart, the C-47 Skytrain, but it was not as extensively produced as the latter.
The Boeing Model 247 was an early United States airliner, considered the first such aircraft to fully incorporate advances such as all-metal semimonocoque construction, a fully cantilevered wing and retractable landing gear. Other advanced features included control surface trim tabs, an autopilot and de-icing boots for the wings and tailplane.
The Boeing C-97 Stratofreighter was a long-range heavy military cargo aircraft developed from the B-29 and B-50 bombers. Design work began in 1942, the first of three prototype XC-97s flew on 9 November 1944, and the first of six service-test YC-97s flew on 11 March 1947. All nine were based on the 24ST alloy structure and Wright R-3350 engines of the B-29, but with a larger-diameter fuselage upper lobe and they had the B-29 vertical tail with the gunner's position blanked off. The first of three heavily revised YC-97A incorporating the re-engineered wing, taller vertical tail and larger Pratt and Whitney R-4360 engines of the B-50 bomber, flew on 28 January 1948 and was the basis of the subsequent sole YC-97B, all production C-97s, KC-97s and civilian Stratocruiser aircraft. Between 1944 and 1958, 888 C-97s in several versions were built, 811 being KC-97 tankers. C-97s served in the Berlin Airlift, the Korean War, and the Vietnam War. Some aircraft served as flying command posts for the Strategic Air Command, while others were modified for use in Aerospace Rescue and Recovery Squadrons (ARRS).
The Grumman G-21 Goose is an amphibious flying boat designed by Grumman to serve as an eight-seat "commuter" aircraft for businessmen in the Long Island area. The Goose was Grumman's first monoplane to fly, its first twin-engined aircraft, and its first aircraft to enter commercial airline service. During World War II, the Goose became an effective transport for the US military, as well as serving with many other air forces. During hostilities, the Goose took on an increasing number of combat and training roles.
The Lockheed Model 14 Super Electra, more commonly known as the Lockheed 14, was a civil passenger and cargo aircraft built by the Lockheed Aircraft Corporation during the late 1930s. An outgrowth of the earlier Model 10 Electra, the Model 14 was also developed into larger, more capable civil and military versions.
The Douglas Dolphin was an American amphibious flying boat. While only 58 were built, they served a wide variety of roles including private air yacht, airliner, military transport, and search and rescue.
The Boeing Model 307 Stratoliner was an American commercial transport aircraft that entered commercial service in July 1940. It was the first to offer a pressurized cabin, allowing it to cruise at an altitude of 20,000 ft (6,000 m), well above many weather disturbances. The pressure differential was 2.5 psi (17 kPa), so at 14,700 ft (4,480 m) the cabin air pressure was equivalent to an altitude of 8,000 ft (2,440 m). The Model 307 had capacity for a crew of six and 33 passengers. The cabin was nearly 12 ft (3.6 m) across. It was the first land-based aircraft to include a flight engineer as a crew member. In addition to its civilian service it was also flown as the Boeing C-75 Stratoliner by the United States Army Air Forces, who used it as a long-range cargolift aircraft.
The Boeing P-12/F4B was an American pursuit aircraft that was operated by the United States Army Air Corps and United States Navy.
The Boeing YB-9 was the first all-metal monoplane bomber aircraft designed for the United States Army Air Corps. The YB-9 was an enlarged alteration of Boeing's Model 200 Monomail commercial transport.
The Northrop A-17, a development of the Northrop Gamma 2F model, was a two-seat, single-engine, monoplane, attack bomber built in 1935 by the Northrop Corporation for the U.S. Army Air Corps. When in British Commonwealth service during World War II, the A-17 was called Nomad.
The Consolidated P-30 (PB-2) was a 1930s United States two-seat fighter aircraft. An attack version called the A-11 was also built, along with two Y1P-25 prototypes and YP-27, Y1P-28, and XP-33 proposals. The P-30 is significant for being the first fighter in United States Army Air Corps service to have retractable landing gear, an enclosed and heated cockpit for the pilot, and an exhaust-driven turbo-supercharger for altitude operation.
The Boeing 80 was an American airliner of the 1920s. A three-engined biplane, the Model 80 was built by the Boeing Airplane Company for Boeing's own airline, Boeing Air Transport, successfully carrying both airmail and passengers on scheduled services.
The Boeing Model 200 Monomail was an American mail plane of the early 1930s.
The Junkers W 34 was a German-built, single-engine, passenger and transport aircraft. Developed in the 1920s, it was taken into service in 1926. The passenger version could take a pilot and five passengers. The aircraft was developed from the Junkers W 33. Further development led to the Junkers Ju 46.
The Fokker F-10 was an enlarged development of the Fokker F.VII airliner, built in the late 1920s by the Fokker Aircraft Corporation of America. It carried 12 passengers, four more than the F.VII, and had a larger wing and more powerful engines.
The Boeing Model 95 was a single engine biplane mailplane built by Boeing in the United States in the late 1920s to supplement the Boeing Model 40s being used on Boeing's airmail routes.
The Fokker F-11 was a luxury flying boat produced as an 'air yacht' in the United States in the late 1920s. Technically the aircraft was the Fokker Aircraft Corporation of America's Model 9. It was sold in North America as the Fokker F-11 and was offered in Europe as the Fokker B.IV. By the time the first six aircraft had been constructed, it was already evident that the design was not going to sell well. A few were sold, two to notable multi-millionaires; Harold Vanderbilt and Garfield Wood each purchasing one. One was bought by Air Ferries in San Francisco. The F-11A cost $40,000 but the price was slashed to $32,500 as the depression set in during 1930. The F-11 was a commercial failure.
The Stearman 4 is an American commercial biplane that was manufactured in the 1920s by Stearman Aircraft. They were marketed at the time as fast and luxurious executive transports and mail planes for about US$16,000.
The Douglas DC-2 is a 14-passenger, twin-engined airliner that was produced by the American company Douglas Aircraft Corporation starting in 1934. It competed with the Boeing 247. In 1935, Douglas produced a larger version called the DC-3, which became one of the most successful aircraft in history.
