Keystone Aircraft
Keystone Aircraft Corporation was an early American airplane manufacturer. History Headquartered in Bristol, Pennsylvania, the company was formed as "Ogdensburg Aeroway Corp" in 1920 by Thomas Huff and Elliot Daland, but its name was quickly changed to " Huff-Daland Aero Corp", then to "Huff-Daland Aero Company". The company made a name for itself in agricultural aircraft, and then in the United States Army Air Corps' early bomber aircraft. From 1924, James McDonnell was the chief designer. In 1926, Huff left the company, and it was soon purchased by Hayden, Stone & Co., who increased capital to $1 million (United States) and renamed it Keystone. In 1928, it merged with Loening and was known as Keystone–Loening. In 1929, it was taken over by Curtiss-Wright. Also in 1929, the Keystone–Loening plant on the East River in New York City was closed by Curtis-Wright and the operation was moved to the Bristol, Pennsylvania. Keystone plant.

Naval Aircraft Factory PN
The Naval Aircraft Factory PN was a series of open cockpit American flying boats of the 1920s and 1930s. A development of the Felixstowe F5L flying boat of the First World War, variants of the PN were built for the United States Navy by Douglas, Keystone and Martin. Development and design The PN flying boats were twin-engine biplanes with their engines mounted in nacelles between the fabric-covered wings. Other than on the PN-11 which had a different hull form, the hull had large chines running back to the first step similar to those on the F.5L. It had a standard crew of five, but was capable of carrying a relief crew for long patrols. Early machines had wood hulls and wings, with the wings covered in fabric, while various versions replaced these with metal components. A wide variety of V-12 and radial engines were fitted, due to problems with several of the engines chosen, with later versions generally using radial engines. At the end of World War I the United States Navy ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Douglas DC-3
The Douglas DC-3 is a propeller-driven airliner manufactured by Douglas Aircraft Company, which had a lasting effect on the airline industry in the 1930s to 1940s and World War II. It was developed as a larger, improved 14-bed sleeper version of the Douglas DC-2. It is a low-wing metal monoplane with conventional landing gear, powered by two radial piston engines of . (Although most DC-3s flying today use Pratt & Whitney R-1830 Twin Wasp engines, many DC-3s built for civil service originally had the Wright R-1820 Cyclone.) The DC-3 has a cruising speed of , a capacity of 21 to 32 passengers or 6,000 lbs (2,700 kg) of cargo, and a range of , and can operate from short runways. The DC-3 had many exceptional qualities compared to previous aircraft. It was fast, had a good range, was more reliable, and carried passengers in greater comfort. Before the war, it pioneered many air travel routes. It was able to cross the continental United States from New York to Los An ...

Sikorsky S-42
The Sikorsky S-42 was a commercial flying boat designed and built by Sikorsky Aircraft to meet requirements for a long-range flying boat laid out by Pan American World Airways (Pan Am) in 1931. The innovative design included wing flaps, variable-pitch propellers, and a tail-carrying full-length hull. The prototype first flew on 29 March 1934, and, in the period of development and test flying that followed, quickly established ten world records for payload-to-height. The "Flying Clipper" and the "Pan Am Clipper" were other names for the S-42. Design and development During the inaugural flight of Sikorsky's previous flying boat, the Sikorsky S-40, S-40, on November 19, 1931, the pilot and Pan American World Airways, Pan American Airways consultant, Charles Lindbergh, who considered the S-40 a monstrosity, engaged designer Igor Sikorsky in a conversation about what he thought the next airplane should look like.Daley, Robert, An American Saga, 1980, Random House, New York, , pages 10 ...

Sikorsky S-41
The Sikorsky S-41 was an amphibious flying boat airliner produced in the United States in the early 1930s. Essentially a scaled-up monoplane version of the Sikorsky S-38 biplane flying boat, Pan Am operated the type on routes in the Caribbean, South America, and between Boston and Halifax. Development The S-41 had a parasol wing configuration, with two radial engines mounted on struts between the fuselage and the wing. The cabin was completely enclosed within the all-metal hull and could seat 15 passengers.Taylor 1989, p.810''The Illustrated Encyclopedia of Aircraft'', p.2932 The United States Navy purchased three examples and designated them RS-1; these were joined by two Pan Am aircraft pressed into Navy service and designated RS-5.

Sikorsky S-40
The Sikorsky S-40 was an American amphibious flying boat built by Sikorsky in the early 1930s for Pan American Airways. Design and development Sikorsky designed the S-40 in response to a request from Juan Trippe, president of Pan American Airways, for a larger passenger-carrying airplane. The S-40 could carry 38 passengers, a significant increase over the S-38's eight passengers. Wind tunnel testing of the S-40 started in October 1928, and models of the hull were tested in April 1929. The aircraft featured a pantry with an electric refrigerator and stove as well as a smoking lounge with book-ended mahogany wood paneling. Six life rafts were carried. Despite a significant size increase over the preceding S-38, the S-40 design was a conservative iteration of the smaller aircraft; the numerous flying wires and strut braces that were used in the exterior support framework caused significant drag and prompted Charles Lindbergh, retained as a consultant for Pan American, to tell Sik ...

Sikorsky S-38
The Sikorsky S-38 was an American twin-engined ten-seat sesquiplane amphibious aircraft. It was Sikorsky's first widely produced amphibious flying boat, serving successfully for Pan American Airways and the United States military. Design and development The S-38 was developed based upon experience with the Sikorsky S-34 and S-36. The S-38 first flew in May 1928. According to Sikorsky, "The ship had very good takeoff characteristics from land and water. It had a climb of per minute fully loaded, and a maximum speed close to . The ship could cruise nicely around , and it stayed in the air on one engine. All these features were excellent for 1928 and at that time there were no other amphibians with such performance characteristics. In 1929, an S-38 was used by Colonel Lindbergh to inaugurate air mail service between the United States and the Panama Canal." The United States Navy ordered two aircraft, and Pan Am was an early customer. A total of 101 aircraft were built, manufactur ...

Jimmie Angel
James "Jimmie" Crawford Angel (August 1, 1899December 8, 1956) was an American aviator after whom Angel Falls in Venezuela, the tallest waterfall in the world, is named. Early life James Crawford Angel was born August 1, 1899, near Cedar Valley, Missouri, the son of Glenn Davis Angel and Margaret Belle (Marshall) Angel. Because his grandfather, James Edward Angel, was living, he was called ''Crawford'' to avoid confusion in the Angel family during his younger years. He is alleged to have been in World War I, but the only certainty is that he registered for the draft on September 12, 1918. In his twenties he adopted the nickname "Jimmie" by which he was known for the rest of his life. Angel Falls The falls, which cascade from the top of Auyantepui in the remote Gran Sabana region of Venezuela, were not known to the outside world until Jimmie Angel flew over them on November 16, 1933 while searching for a valuable ore bed. On October 9, 1937, he returned to the falls with the i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Metal Aircraft Corporation Flamingo
The Metal Aircraft Flamingo was a monoplane produced in Cincinnati, Ohio by the Metal Aircraft Corporation in the 1930s. Design and development The Metal Aircraft Corporation purchased the design from the Halpin Development Co. and unveiled it at the 1929 National Air Races with Elinor Smith. Following an accident at Bowman Field in May 1928, the prototype Flamingo was redesigned with a different nose, windscreen, and tail. The interior was insulated with Balsam-Wool Blanket. Operational history The Flamingo was first flown from Lunken Airport on 8 April 1928 by Thomas E. Halpin. At one point, the aircraft carried an African-American porter in a red suit named Benny Smith. Following a teaser, marketing for the new airplane began in March 1929 and dealers were being solicited by the following month. One G-2-W, named ''El Rio Caroní'', is best remembered for its role in the discovery of Angel Falls by Jimmy Angel in 1935. Although well known to the local indigenous population ...
