United Airlines Flight 736
United Air Lines Flight 736 was a scheduled transcontinental passenger service flown daily by United Airlines between Los Angeles and New York City. On April21, 1958, the airliner assigned to the flight, a Douglas DC-7 with 47 on board, was flying over Clark County, Nevada in clear weather when it was involved in a daytime with a United States Air Force fighter jet crewed by two pilots. Both aircraft fell out of control from and crashed into unpopulated desert terrain southwest of Las Vegas, leaving no survivors. The loss of Flight 736, one of a series of 1950s mid-air collisions involving passenger aircraft in American skies, helped usher-in widespread improvements in air traffic control within the United States, and led to a sweeping reorganization of federal government aviation authorities. Among the DC-7 passengers were a group of military personnel and civilian contractors involved with sensitive United States Department of Defense, Department of Defense weapons systems. ...

Pacific Time Zone
The Pacific Time Zone (PT) is a time zone encompassing parts of western Canada, the western United States, and western Mexico. Places in this zone observe standard time by subtracting eight hours from Coordinated Universal Time ( UTC−08:00). During daylight saving time, a time offset of UTC−07:00 is used. In the United States and Canada, this time zone is generically called the Pacific Time Zone. Specifically, time in this zone is referred to as Pacific Standard Time (PST) when standard time is being observed (early November to mid-March), and Pacific Daylight Time (PDT) when daylight saving time (mid-March to early November) is being observed. In Mexico, the corresponding time zone is known as the ''Zona Noroeste'' (Northwest Zone) and observes the same daylight saving schedule as the United States and Canada. The largest city in the Pacific Time Zone is Los Angeles, whose metropolitan area is also the largest in the time zone. The zone is two hours ahead of the Ha ...

Nellis Air Force Base
Nellis Air Force Base ("Nellis" colloquialism, colloq.) is a United States Air Force military installation, installation in southern Nevada. Nellis hosts Aerial warfare, air combat exercises such as Exercise Red Flag and close air support exercises such as Green Flag-West flown in "Military Operations Area, Military Operations Area (MOA) airspace", associated with the nearby Nevada Test and Training Range (NTTR). The base also has the Combined Air and Space Operations Center-Nellis. History After World War I, Nevada and other western inland states were surveyed by Capt. Lowell H. Smith and Sgt. William B. Whitefield for landing sites, and by "mid-1925 the Air Service possessed information on nearly thirty-five hundred landing places, including more than twenty-eight hundred emergency landing areas, in the United States." The 1929 airfield (dirt runway, water well, and small operations shack) north of Las Vegas—operated by the 1925 Western Air Express for Contract Air Mail ( ...

United Press
United Press International (UPI) is an American international news agency whose newswires, photo, news film, and audio services provided news material to thousands of newspapers, magazines, radio and television stations for most of the 20th century until its eventual decline beginning in the early 1980s. At its peak, it had more than 6,000 media subscribers. Since the first of several sales and staff cutbacks in 1982, and the 1999 sale of its broadcast client list to its main U.S. rival, the Associated Press, UPI has concentrated on smaller information-market niches. History Formally named United Press Associations for incorporation and legal purposes but publicly known and identified as United Press or UP, the news agency was created by the 1907 uniting of three smaller news syndicates by the Midwest newspaper publisher E. W. Scripps. It was headed by Hugh Baillie (1890–1966) from 1935 to 1955. At the time of his retirement, UP had 2,900 clients in the United States, an ...

Iconorama
Iconorama was a Cold War electronic projection system for graphic presentation ("stylized display using an etched plate to produce symbols") developed by the firm Fenske, Fedrick and Miller. The Iconorama was ordered by the United States Air Force in 1959. The mechanism used a rear projection display, showing both a map overlay from a fixed lantern slide and dynamically updated data from a mechanical plotter. The mechanism for etching the slide is somewhat similar to an Etch A Sketch. The display can draw lines and characters, but cannot erase them individually. The unit was used in the IBM 473L Command and Control System's Large Panel Display Subsystem (e.g., at the National Military Command Center and the Raven Rock Mountain Complex, Alternate Military Command Center). Advertised in 1961 by Temco Aircraft, Temco Aircraft Corp.

Flight Engineer
A flight engineer (FE), also sometimes called an air engineer, is a member of an aircraft's flight crew who is responsible for monitoring and operating its complex aircraft systems. In the early era of aviation, the position was sometimes referred to as the "air mechanic". Flight engineers can still be found on some larger Fixed-wing aircraft, fixed-wing airplanes and helicopters. A similar crew position exists on some spacecraft. In most modern aircraft, their complex systems are both monitored and adjusted by electronic microprocessors and computers, resulting in the elimination of the flight engineer's position. In earlier days, most larger aircraft were designed and built with a flight engineer's position. For U.S. civilian aircraft that require a flight engineer as part of the crew, the flight engineer must possess an FAA Flight Engineer Certificate with reciprocating, turboprop, or turbojet ratings appropriate to the aircraft. Whereas the four-engine Douglas DC-4 did not re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
Propliner
A propliner is a large, propeller-driven airliner. Typically, the term is used for piston engine airliners that flew before the large scale advent of airliners of the jet age. With the notable exception of the de Havilland Albatross and Fokker F-10 of the late 1920s to 1930s, which were largely fabricated of wood, propliners generally featured all-metal wings and structural members, totally or partially retractable landing gear, and two, three, or four engines. A few might deviate from these characteristics with fixed landing gear, such as the Albatross, Fokker 110, and Lockheed Vega. The first all metal passenger service propliner was the Handley Page Type W in the 1920s. Then the Boeing 247 made its first flight in 1933, with the Douglas DC-1 and Douglas DC-2 closely following in response. The most successful is the Douglas DC-3, which was produced in the thousands, and is still in widespread use; while the Dewoitine D.338 and SNCASE SE.161 Languedoc were developed in Fra ...

Airway (aviation)
In the United States, airways or air routes are defined by the Federal Aviation Administration (FAA) in two ways: "VOR Federal airways and Low/Medium Frequency (L/MF) (Colored) Federal airways" These are designated routes which aeroplanes fly to aid in navigation and help with separation to avoid accidents. Airways are defined with segments within a specific altitude block, corridor width, and between fixed geographic coordinates for satellites navigation system, or between ground-based radio transmitter navigational aids (navaids; such as VORs or NDBs) or the intersection of specific radials of two navaids. United States History To guide airmail pilots on their delivery routes, the United States Postal Service constructed the first airways in the United States, the Contract Air Mail routes. These airways were between major cities and identified at night by a series of flashing lights and beacons which pilots flew over in sequence to get from one city to the next. Int ...

Cockpit
A cockpit or flight deck is the area, on the front part of an aircraft, spacecraft, or submersible, from which a pilot controls the vehicle. The cockpit of an aircraft contains flight instruments on an instrument panel, and the controls that enable the pilot to fly the aircraft. In most airliners, a door separates the cockpit from the aircraft cabin. After the September 11, 2001 attacks, all major airlines fortified their cockpits against access by hijackers. Etymology The word cockpit seems to have been used as a nautical term in the 17th century, without reference to cock fighting. It referred to an area in the rear of a ship where the cockswain's station was located, the cockswain being the pilot of a smaller "boat" that could be dispatched from the ship to board another ship or to bring people ashore. The word "cockswain" in turn derives from the old English terms for "boat-servant" (''coque'' is the French word for "shell"; and ''swain'' was old English for boy ...

Air Traffic Control
Air traffic control (ATC) is a service provided by ground-based air traffic controllers who direct aircraft on the ground and through a given section of controlled airspace, and can provide advisory services to aircraft in non-controlled airspace. The primary purpose of ATC is to prevent collisions, organise and expedite the flow of traffic in the air, and provide information and other support for pilots. Personnel of air traffic control monitor aircraft location in their assigned airspace by radar and communicate with the pilots by radio. To prevent collisions, ATC enforces Separation (air traffic control), traffic separation rules, which ensure each aircraft maintains a minimum amount of 'empty space' around it at all times. It is also common for ATC to provide services to all General aviation, private, Military aviation, military, and commercial aircraft operating within its airspace; not just civilian aircraft. Depending on the type of flight and the class of airspace, AT ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] [Amazon] |
