Holman Field Administration Building
The Holman Field Administration Building is a Kasota limestone building designed by Clarence Wigington and built in 1939 by WPA employees. It serves as the control building for the St. Paul Downtown Airport in Saint Paul in the U.S. state of Minnesota. The airport was named for Charles W. Holman, who won the U.S. air speed trials in 1930. The airfield was built on the former site of Lamprey Lake, which was filled with dredged material from the adjacent Mississippi River, which regularly floods the airport. Across the river in Indian Mounds Park is one of the last remaining airway beacons in the country. During World War II, Northwest Airlines employed up to 5000 people at the site, modifying new B-24 Liberator bombers, some of which received the highly classified H2X radar Radar is a detection system that uses radio waves to determine the distance ('' ranging''), angle, and radial velocity of objects relative to the site.

Saint Paul, Minnesota
Saint Paul (abbreviated St. Paul) is the capital of the U.S. state of Minnesota and the county seat of Ramsey County. Situated on high bluffs overlooking a bend in the Mississippi River, Saint Paul is a regional business hub and the center of Minnesota's government. The Minnesota State Capitol and the state government offices all sit on a hill close to the city's downtown district. One of the oldest cities in Minnesota, Saint Paul has several historic neighborhoods and landmarks, such as the Summit Avenue Neighborhood, the James J. Hill House, and the Cathedral of Saint Paul. Like the adjacent and larger city of Minneapolis, Saint Paul is known for its cold, snowy winters and humid summers. As of the 2021 census estimates, the city's population was 307,193, making it the 67th-largest city in the United States, the 12th-most populous in the Midwest, and the second-most populous in Minnesota. Most of the city lies east of the Mississippi River near its confluence with the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Northwest Airlines
Northwest Airlines Corp. (NWA) was a major American airline founded in 1926 and absorbed into Delta Air Lines, Inc. by a merger. The merger, approved on October 29, 2008, made Delta the largest airline in the world until the American Airlines-US Airways merger on December 9, 2013. Northwest continued to operate under its own name and brand until the integration of the carriers was completed on January 31, 2010. Northwest was headquartered in Eagan, Minnesota near Minneapolis-St. Paul International Airport. After World War II it became dominant in the trans-Pacific market with a hub in Tokyo, Japan (initially Haneda Airport, later Narita International Airport). In response to United Airlines's 1985 acquisition of Pan Ams' Pacific routes, Northwest paid $884 million to purchase Republic Airlines and then established fortress hubs at Detroit Metropolitan Wayne County Airport and Memphis International Airport. With this merger, NWA established the domestic network necess ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Buildings And Structures Completed In 1939
A building, or edifice, is an enclosed structure with a roof and walls standing more or less permanently in one place, such as a house or factory (although there's also portable buildings). Buildings come in a variety of sizes, shapes, and functions, and have been adapted throughout history for a wide number of factors, from building materials available, to weather conditions, land prices, ground conditions, specific uses, prestige, and aesthetic reasons. To better understand the term ''building'' compare the list of nonbuilding structures. Buildings serve several societal needs – primarily as shelter from weather, security, living space, privacy, to store belongings, and to comfortably live and work. A building as a shelter represents a physical division of the human habitat (a place of comfort and safety) and the ''outside'' (a place that at times may be harsh and harmful). Ever since the first cave paintings, buildings have also become objects or canvasses of much artist ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Air Transportation Buildings And Structures On The National Register Of Historic Places
The atmosphere of Earth is the layer of gases, known collectively as air, retained by Earth's gravity that surrounds the planet and forms its planetary atmosphere. The atmosphere of Earth protects life on Earth by creating pressure allowing for liquid water to exist on the Earth's surface, absorbing ultraviolet solar radiation, warming the surface through heat retention (greenhouse effect), and reducing temperature extremes between day and night (the diurnal temperature variation). By mole fraction (i.e., by number of molecules), dry air contains 78.08% nitrogen, 20.95% oxygen, 0.93% argon, 0.04% carbon dioxide, and small amounts of other gases. Air also contains a variable amount of water vapor, on average around 1% at sea level, and 0.4% over the entire atmosphere. Air composition, temperature, and atmospheric pressure vary with altitude. Within the atmosphere, air suitable for use in photosynthesis by terrestrial plants and breathing of terrestrial animals is found only in Ea ...

Radar
Radar is a detection system that uses radio waves to determine the distance ('' ranging''), angle, and radial velocity of objects relative to the site. It can be used to detect aircraft, ships, spacecraft, guided missiles, motor vehicles, weather formations, and terrain. A radar system consists of a transmitter producing electromagnetic waves in the radio or microwaves domain, a transmitting antenna, a receiving antenna (often the same antenna is used for transmitting and receiving) and a receiver and processor to determine properties of the objects. Radio waves (pulsed or continuous) from the transmitter reflect off the objects and return to the receiver, giving information about the objects' locations and speeds. Radar was developed secretly for military use by several countries in the period before and during World War II. A key development was the cavity magnetron in the United Kingdom, which allowed the creation of relatively small systems with sub-meter resolution ...

H2X Radar
H2X, officially known as the AN/APS-15, was an American ground scanning radar system used for blind bombing during World War II. It was a development of the British H2S radar, the first ground mapping radar to be used in combat. It was also known as the "Mickey set" and "BTO" for "bombing through the overcast" radar. H2X differed from the original H2S primarily in its X band 10 GHz operating frequency rather than H2S' S band 3 GHz emissions. This gave H2X higher resolution than H2S, allowing it to provide usable images over large cities which appeared as a single blob on the H2S display. The Royal Air Force (RAF) initially considered using H2X as well, but would instead develop their own X band system, the H2S Mk. III. The RAF system entered service in late 1943, before the first use of H2X in early 1944. The desire for even higher resolution, enough to image individual docks and bridges, led to a number of variations on the H2X system, as well as the more advanced A ...

B-24 Liberator
The Consolidated B-24 Liberator is an American heavy bomber, designed by Consolidated Aircraft of San Diego, California. It was known within the company as the Model 32, and some initial production aircraft were laid down as export models designated as various LB-30s, in the Land Bomber design category. At its inception, the B-24 was a modern design featuring a highly efficient shoulder-mounted, high aspect ratio Davis wing. The wing gave the Liberator a high cruise speed, long range and the ability to carry a heavy bomb load. Early RAF Liberators were the first aircraft to cross the Atlantic Ocean as a matter of routine. In comparison with its contemporaries, the B-24 was relatively difficult to fly and had poor low-speed performance; it also had a lower ceiling and was less robust than the Boeing B-17 Flying Fortress. While aircrews tended to prefer the B-17, General Staff favored the B-24 and procured it in huge numbers for a wide variety of roles. At approximately ...

World War II
World War II or the Second World War, often abbreviated as WWII or WW2, was a world war that lasted from 1939 to 1945. It involved the World War II by country, vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies of World War II, Allies and the Axis powers. World War II was a total war that directly involved more than 100 million Military personnel, personnel from more than 30 countries. The major participants in the war threw their entire economic, industrial, and scientific capabilities behind the war effort, blurring the distinction between civilian and military resources. Air warfare of World War II, Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the Atomic bombings of Hiroshima and Nagasaki, only two nuclear weapons ever used in war. World War II was by far the List of wars by death toll, deadliest conflict in hu ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Clarence Wigington
Clarence Wesley "Cap" Wigington (1883-1967) was an American architect who grew up in Omaha, Nebraska. After winning three first prizes in charcoal, pencil, and pen and ink at an art competition during the Trans-Mississippi Exposition in 1899, Wigington went on to become a renowned architect across the Midwestern United States, at a time when African-American architects were few. Wigington was the nation's first black municipal architect, serving 34 years as senior designer for the City of Saint Paul, Minnesota's architectural office when the city had an ambitious building program. Sixty of his buildings still stand in St. Paul, with several recognized on the National Register of Historic Places. Wigington's architectural legacy is one of the most significant bodies of work by an African-American architect.Taylor, D.V. (2002) p 4.
