Albert F. Hegenberger
Albert Francis Hegenberger (September 30, 1895 – August 31, 1983) was a major general in the United States Air Force and a pioneering aviator who set a flight distance record with Lester J. Maitland, completing the first transpacific flight to Hawaii in 1927 as navigator of the ''Bird of Paradise''. Hegenberger was an aeronautical engineer of note, earning both the Mackay Trophy (1927) and Collier Trophy (1934) for achievement. Hegenberger also invented the non-directional beacon, adopted for both military and civil use. Biography Early years and World War I Hegenberger was born at Boston, Massachusetts, in 1895.

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 vast majority of the world's countries—including all of the great powers—forming two opposing military alliances: the Allies and the Axis powers. World War II was a total war that directly involved more than 100 million 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. Aircraft played a major role in the conflict, enabling the strategic bombing of population centres and deploying the only two nuclear weapons ever used in war. World War II was by far the deadliest conflict in human history; it resulted in 70 to 85 million fatalities, mostly among civilians. Tens of millions died due to genocides (including the Holocaust), starvation, ma ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

World War I
World War I (28 July 1914 11 November 1918), often abbreviated as WWI, was one of the deadliest global conflicts in history. Belligerents included much of Europe, the Russian Empire, the United States, and the Ottoman Empire, with fighting occurring throughout Europe, the Middle East, Africa, the Pacific, and parts of Asia. An estimated 9 million soldiers were killed in combat, plus another 23 million wounded, while 5 million civilians died as a result of military action, hunger, and disease. Millions more died in genocides within the Ottoman Empire and in the 1918 influenza pandemic, which was exacerbated by the movement of combatants during the war. Prior to 1914, the European great powers were divided between the Triple Entente (comprising France, Russia, and Britain) and the Triple Alliance (containing Germany, Austria-Hungary, and Italy). Tensions in the Balkans came to a head on 28 June 1914, following the assassination of Archduke Franz Ferdin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Civil Engineering
Civil engineering is a professional engineering discipline that deals with the design, construction, and maintenance of the physical and naturally built environment, including public works such as roads, bridges, canals, dams, airports, sewage systems, pipelines, structural components of buildings, and railways. Civil engineering is traditionally broken into a number of sub-disciplines. It is considered the second-oldest engineering discipline after military engineering, and it is defined to distinguish non-military engineering from military engineering. Civil engineering can take place in the public sector from municipal public works departments through to federal government agencies, and in the private sector from locally based firms to global Fortune 500 companies. History Civil engineering as a discipline Civil engineering is the application of physical and scientific principles for solving the problems of society, and its history is intricately linked to advances in t ...

Non-directional Beacon
A non-directional beacon (NDB) or non-directional radio beacon is a radio beacon which does not include directional information. Radio beacons are radio transmitters at a known location, used as an aviation or marine navigational aid. NDB are in contrast to directional radio beacons and other navigational aids, such as low-frequency radio range, VHF omnidirectional range (VOR) and tactical air navigation system (TACAN). NDB signals follow the curvature of the Earth, so they can be received at much greater distances at lower altitudes, a major advantage over VOR. However, NDB signals are also affected more by atmospheric conditions, mountainous terrain, coastal refraction and electrical storms, particularly at long range. The system, developed by United States Air Force (USAF) Captain Albert Francis Hegenberger, was used to fly the world's first instrument approach on May 9, 1932. Types of NDBs NDBs used for aviation are standardised by International Civil Aviation Organizat ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Collier Trophy
The Robert J. Collier Trophy is an annual aviation award administered by the U.S. National Aeronautic Association (NAA), presented to those who have made "the greatest achievement in aeronautics or astronautics in America, with respect to improving the performance, efficiency, and safety of air or space vehicles, the value of which has been thoroughly demonstrated by actual use during the preceding year." Robert J. Collier, publisher of ''Collier's Weekly'' magazine, was an air sports pioneer and president of the Aero Club of America. In 1910, he commissioned Baltimore sculptor Ernest Wise Keyser to make the ''Aero Club of America Trophy''. First awarded in 1911 to Glenn H. Curtiss for his successful development of the hydro-aeroplane. Collier owned a Wright Model B biplane which he purchased in 1911. Collier presented his namesake trophy several times before his death in 1918; after his World War I service. In 1922, when the Aero Club dissolved, the award was taken over ...

Bird Of Paradise (aircraft)
The ''Bird of Paradise'' was a military airplane used by the United States Army Air Corps in 1927 to experiment with the application of radio beacon aids in air navigation. On June 28–29, 1927, the ''Bird of Paradise'', crewed by 1st Lt. Lester J. Maitland and 1st Lt. Albert F. Hegenberger, completed the first flight over the Pacific Ocean from the mainland, California, to Hawaii. For this feat the crew received the Mackay Trophy. The ''Bird of Paradise'' was one of three Atlantic-Fokker C-2 tri-motor transport aircraft developed for the Air Corps from the civilian Fokker F.VIIa/3m airliner design. Its two-ton carrying capacity gave it the ability to carry sufficient fuel for the flight and its three motors provided an acceptable safety factor in the event one engine failed. Moreover, although modified for the long distance flight, the C-2 was a widely used standard design, demonstrating the practicality of flying long distances. Although the recognition accorded Maitland a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
