Edmund T. Allen
Edmund Turney Allen (January 4, 1896 – February 18, 1943) was a pioneer of modern flight test who flew for nearly every major American aircraft manufacturer and took some of the most famous planes of all time up for their first flights. Early life Allen was born in Chicago, Illinois on 4 January 1896. He had to work for three years after his father died to support his family. He then finished one year at the University of Illinois. Career World War I When the United States entered World War I, he enlisted in the US Army Signal Corps as a lieutenant. He initially served as an instructor pilot but then was sent to the British flight test center in England to learn flight testing techniques. Before the armistice in November 1918, he returned to the US Army's flight test center at McCook Field, Ohio, to apply his flight experience and overseas observations. After the armistice, he became the first test pilot for the National Advisory Committee on Aeronautics at Langley Field, Vir ...

United States Post Office Department
The United States Post Office Department (USPOD; also known as the Post Office or U.S. Mail) was the predecessor of the United States Postal Service, in the form of a Cabinet department, officially from 1872 to 1971. It was headed by the postmaster general. The Postal Service Act, signed by U.S. president George Washington on February 20, 1792, established the department. Postmaster General John McLean, in office from 1823 to 1829, was the first to call it the Post Office ''Department'' rather than just the "Post Office." The organization received a boost in prestige when President Andrew Jackson invited his postmaster general, William T. Barry, to sit as a member of the Cabinet in 1829. The Post Office Act of 1872 () elevated the Post Office Department to Cabinet status. During the American Civil War (1861–1865), postal services in the Confederate States of America were provided by the Confederate States of America Post-office Department, headed by Postmaster General John He ...

Northrop Gamma
The Northrop Gamma was a single-engine all-metal monoplane cargo aircraft used in the 1930s. Towards the end of its service life, it was developed into the A-17 light bomber. Design and development The Gamma was a further development of the successful Northrop Alpha and shared its predecessor's aerodynamic innovations with wing fillets and multicellular stressed-skin wing construction. Like late Alphas, the fixed landing gear was covered in distinctive aerodynamic spats, and the aircraft introduced a fully enclosed cockpit. Operational history The Gamma saw fairly limited civilian service as mail planes with Trans World Airlines but had an illustrious career as a flying laboratory and record-breaking aircraft. The US military found the design sufficiently interesting to encourage Northrop to develop it into what eventually became the Northrop A-17 light attack aircraft. Military versions of the Gamma saw combat with Chinese and Spanish Republican air forces.Smith 1986 Twenty ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northrop Beta
The Northrop Beta was an American single-engine, all-metal, low-wing sporting monoplane built in 1931. Design and development The Beta was a two-seater with a 160 hp (119 kW) Menasco Buccaneer inline engine. The first aircraft registered as NX963Y (later NC963Y) crashed in California. The second aircraft, N12214, was built as a single-seater and fitted with a 300 hp (224 kW) Pratt & Whitney Wasp Jr. radial engine, and became the first aircraft of such power to exceed 200 mph (322 km/h). Only two were built. The aircraft was flown to Wichita for sister company Stearman Aircraft to use as a demonstrator but with the poor economy at the time, none were sold. The aircraft was sold to a wealthy pilot in New York and during its delivery, it passed through Wright Field in order to allow a thorough examination by Army Air Corps Engineers as the Air Corps was still using obsolete biplanes. After being rarely flown during 1932, the aircraft was sold to a new ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Boeing Monomail
The Boeing Model 200 Monomail was an American mail plane of the early 1930s. Design and development The aircraft marked a departure from the traditional biplane configuration for a transport aircraft, instead featuring a single, low set, all metal cantilever wing. Retractable landing gear and a streamlined fuselage added to the aerodynamic efficiency of the aircraft. A single example was constructed for evaluation by both Boeing and the US Army (under the designation Y1C-18) but no mass production ensued, and the aircraft eventually joined Boeing's fleet on the San Francisco-Chicago air mail route from July 1931. A second version was developed as the Model 221, with a fuselage stretched by 8 inches (20 cm) that sacrificed some of its cargo capacity to carry six passengers in an enclosed cabin; the single pilot, however, sat in an open cockpit. This version first flew on 18 August 1930. Both the Model 200 and the Model 221 were eventually modified for transcontinental ser ...

Northrop Alpha
The Northrop Alpha was an American single-engine, all-metal, seven-seat, low-wing monoplane fast mail/passenger transport aircraft used in the 1930s. Design work was done at the Avion Corporation, which in 1929, became the Northrop Aircraft Corporation based in Burbank, California. Design and development Drawing on his experience with the Lockheed Vega, John K. Northrop designed an advanced mail/passenger transport aircraft. In addition to all-metal construction, the new Alpha benefitted from two revolutionary aerodynamic advancements: wing fillets researched at the Guggenheim Aeronautical Laboratory at the California Institute of Technology, and a multicellular stressed-skin wing of Northrop's own design which was later successfully used on the Douglas DC-2 and Douglas DC-3. In addition, the Alpha was the first commercial aircraft to use rubber deicer boots on wing and empennage leading edges which, in conjunction with state-of-the-art radio navigation equipment, gave it day o ...

Boeing P-12
The Boeing P-12/F4B was an American pursuit aircraft that was operated by the United States Army Air Corps , United States Marine Corps, and United States Navy. Design and development Developed as a private venture to replace the Boeing F2B and F3B with the United States Navy, the Boeing Model 99 first flew on 25 June 1928. The new aircraft was smaller, lighter and more agile than the ones it replaced but still used the Wasp engine of the F3B. This resulted in a higher top speed and overall better performance. As result of Navy evaluation 27 were ordered as the F4B-1; later evaluation by the United States Army Air Corps resulted in orders with the designation P-12. Boeing supplied the USAAC with 366 P-12s between 1929 and 1932. Production of all variants totaled 586. F4B-1 (Boeing Model 99) The F4B-1 was built using typical construction techniques of the day with a welded truss fuselage with formers and longerons to define the aerodynamic shape. Wings were of wood construct ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
