Sikorsky S-29
The Sikorsky S-29-A was a twin-engine sesquiplane airliner, first flown in 1924. It was the first aircraft that aviation pioneer Igor Sikorsky designed and built after coming to the United States, hence the special "-A" suffix signifying "America". The aircraft made many successful long-range flights, most of which Sikorsky piloted himself. The S-29-A claims a number of "firsts" in aviation, including the first twin-engine aircraft capable of maintaining altitude on one engine, the first aircraft to broadcast a radio musical program in-flight, in 1925 and in 1926 the first aircraft to display a motion picture in flight. The S-29-A was also one of the first aircraft to make use of an airstair door, located on the starboard side of the fuselage. Design and development Sikorsky and his colleagues began work on the machine in the spring of 1923 on a farm near Roosevelt Field on Long Island. The aircraft structure was manufactured from steel with the two bay wire-braced strutted wings ...

Grace Coolidge
Grace Anna Coolidge (née Goodhue; January 3, 1879 – July 8, 1957) was first lady of the United States from 1923 to 1929 as the wife of the 30th president of the United States, Calvin Coolidge. She was previously the second lady of the United States from 1921 to 1923 and the first lady of Massachusetts from 1919 to 1921. Coolidge was raised in Burlington, Vermont, and attended the University of Vermont where she co-founded the school's chapter of Pi Beta Phi. She moved to Northampton, Massachusetts, to teach at Clarke School for the Deaf. She met Calvin Coolidge in Northampton, and they married in 1905, having two sons.

Biplanes
A biplane is a fixed-wing aircraft with two main wings stacked one above the other. The first powered, controlled aeroplane to fly, the Wright Flyer, used a biplane wing arrangement, as did many aircraft in the early years of aviation. While a biplane wing structure has a structural advantage over a monoplane, it produces more drag (aerodynamics), drag than a monoplane wing. Improved structural techniques, better materials and higher speeds made the biplane configuration obsolete for most purposes by the late 1930s. Biplanes offer several advantages over conventional cantilever monoplane designs: they permit lighter wing structures, low wing loading and smaller span for a given wing area. However, interference between the airflow over each wing increases drag substantially, and biplanes generally need extensive bracing, which causes additional drag. Biplanes are distinguished from tandem wing arrangements, where the wings are placed forward and aft, instead of above and below. ...

Sikorsky Aircraft
Sikorsky Aircraft is an American aircraft manufacturer based in Stratford, Connecticut. It was established by the Russian-American aviation pioneer Igor Sikorsky in 1923, and was among the first companies to manufacture helicopters for civilian and military use. It also produced seaplanes for passenger transport and surface vehicles such as trains and boats. Sikorsky was owned by United Technologies Corporation until November 2015, when it was sold to Lockheed Martin. History On March 5, 1923, the Sikorsky Aero Engineering Corporation was founded near Roosevelt Field (airport), Roosevelt Field, New York, by Igor Sikorsky, an immigrant to the United States who was born in Kyiv, Kiev, in the Russian Empire (today in Ukraine). In 1925, the company name was changed to Sikorsky Manufacturing Company. After the success of the Sikorsky S-38, S-38, the company was reorganized as the Sikorsky Aviation Corporation with capital of $5,000,000, allowing the purchase of land and the buildin ...

V12 Engine
A V12 engine is a twelve-Cylinder (engine), cylinder Internal combustion engine#Reciprocating engines, piston engine where two banks of six cylinders are arranged in a V engine, V configuration around a common crankshaft. V12 engines are more common than V10 engines. However, they are less common than V8 engines. The first V12 engine was built in 1904 for use in Boat racing, racing boats. Due to the balanced nature of the engine and the smooth delivery of Engine power, power, V12 engines were found in early luxury automobiles, boats, aircraft, and tanks. Aircraft V12 engines reached their apogee during World War II, after which they were mostly replaced by jet engines. In Formula One racing, V12 engines were common during the late 1960s and early 1990s. Applications of V12 engines in the 21st century have been as marine engines, in railway locomotives, as large stationary power as well as in some European sports and luxury cars. Design Balance and smoothness Each bank of a ...

Linen
Linen () is a textile made from the fibers of the flax plant. Linen is very strong and absorbent, and it dries faster than cotton. Because of these properties, linen is comfortable to wear in hot weather and is valued for use in garments. Linen textiles can be made from flax plant fiber, yarn, as well as woven and knitted. Linen also has other distinctive characteristics, such as its tendency to wrinkle. It takes significantly longer to harvest than a material like cotton, although both are natural fibers. It is also more difficult to weave than cotton. Linen textiles appear to be some of the oldest in the world; their history goes back many thousands of years. Dyed flax fibers found in a cave in the Caucasus (present-day Georgia (country), Georgia) suggest the use of woven linen fabrics from wild flax may date back over 30,000 years. Linen was used in ancient civilizations including Mesopotamia and ancient Egypt, and linen is mentioned in the Bible. In the 18th century and be ...

Heavy Bomber
Heavy bombers are bomber Fixed-wing aircraft, aircraft capable of delivering the largest payload of air-to-ground weaponry (usually Aerial bomb, bombs) and longest range (aeronautics), range (takeoff to landing) of their era. Archetypal heavy bombers have therefore usually been among the largest and most powerful Military aviation, military aircraft at any point in time. In the second half of the 20th century, heavy bombers were largely superseded by strategic bombers, which were often even larger in size, had much longer ranges and were capable of delivering nuclear bombs. Because of advances in Aerospace engineering, aircraft design and engineering — especially in Aircraft engine, powerplants and aerodynamics — the size of payloads carried by heavy bombers has increased at rates greater than increases in the size of their airframes. The largest bombers of World War I, the ''Riesenflugzeuge'' of Germany, could carry a payload of up to of bombs; by the latter half of World ...

Gothaer Waggonfabrik
''Gothaer Waggonfabrik'' (''Gotha'', GWF) was a German manufacturer of rolling stock established in the late nineteenth century at Gotha. During the two world wars, the company expanded into aircraft building. World War I In World War I, Gotha was the manufacturer of a highly successful series of bombers based on a 1914 design by Oskar Ursinus and developed by Hans Burkhard. From 1917, the Burkhard-designed twin pusher biplane bomber aircraft were capable of carrying out strategic bombing missions over England, the first heavier-than-air aircraft used in this role. Several dozen of these bombers were built in a number of subtypes - the Ursinus-based Gotha G.I, and the succeeding Burkhard-designed G.II, G.III, G.IV, and G.V. This last variant was the most prolific, with thirty-six in squadron service at one point. Inter war years Whilst Germany was prohibited from military aircraft manufacture by the Treaty of Versailles, Gotha returned to its railway endeavours, but ...

Hell's Angels (film)
''Hell's Angels'' is a 1930 American pre-Code independent epic war film directed and produced by Howard Hughes and director of dialogue James Whale. Written by Harry Behn and Howard Estabrook and starring Ben Lyon, James Hall and Jean Harlow, it was released through United Artists. It follows two dissimilar brothers, both members of the British Royal Flying Corps during the First World War. The film was originally shot as a silent film. '' The Jazz Singer'', which ushered in the sound era, premiered several weeks before the start of principal photography for ''Hell's Angels'' and left the public clamoring for talking pictures. A year and a half later, Hughes decided to convert his film to sound. The original female lead, Norwegian-American Greta Nissen, had to be replaced due to her accent. Jean Harlow became a major star as her successor. The production took three years (1927–1930) and Hughes spared no expense, so that despite being one of the highest-grossing fil ...

Howard Hughes
Howard Robard Hughes Jr. (December 24, 1905 – April 5, 1976) was an American Aerospace engineering, aerospace engineer, business magnate, film producer, and investor. He was The World's Billionaires, one of the richest and most influential people in the world during his lifetime. He first became prominent as a film producer, and then as an important figure in the aviation industry. Later in life, he became known for his eccentric behavior and reclusive lifestyle—oddities that were caused in part by his worsening obsessive-compulsive disorder (OCD), chronic pain from a near-fatal plane crash, and increasing deafness. As a film tycoon, Hughes gained fame in Hollywood beginning in the late 1920s, when he produced big-budget and often controversial films such as ''The Racket (1928 film), The Racket'' (1928), ''Hell's Angels (film), Hell's Angels'' (1930), and ''Scarface (1932 film), Scarface'' (1932). He later acquired the RKO Pictures film studio in 1948, recognized then as one ...
