United Airlines Flight 615
United Air Lines Flight 615 was a US transcontinental east–west airline service from Boston to Hartford, Cleveland, Chicago, Oakland and San Francisco. On August 24, 1951, the Douglas DC-6 with registration operating the service, crashed on approach to Oakland, causing the death of all 44 passengers and 6 crew members on board. The flight departed Chicago at 10:59 p.m. CST en route to Oakland. At around 4:16 a.m., the plane was approaching Oakland. At this time, the pilot, Marion W. Hedden of Los Altos, had talked with the control tower of the Civil Aeronautics Administration at the airport preparing for his landing, and had mentioned no trouble. At 4:25 a.m. Flight 615 was cleared for the straight-in approach into Oakland. This approach clearance was the last radio transmission with the flight. The plane crashed into mountainous terrain southeast of Oakland, careening into Tolman Peak and over its knoll, scattering on the downslope and into Dry Gulch Canyon b ...

Controlled Flight Into Terrain
In aviation, a controlled flight into terrain (CFIT; usually ) is an aviation accidents and incidents, accident in which an airworthy aircraft, under aircraft pilot, pilot control, is unintentionally flown into the ground, a mountain, a body of water or an obstacle. In a typical CFIT scenario, the aircrew, crew is unaware of the impending disaster until it is too late. The term was coined by engineers at Boeing in the late 1970s. Accidents where the aircraft is out of control at the time of impact, because of mechanical failure or pilot error, are not considered CFIT (they are known as ''uncontrolled flight into terrain'' or ''UFIT''), nor are incidents resulting from the deliberate action of the person at the controls, such as acts of terrorism or suicide by pilot. According to Boeing in 1997, CFIT was a leading cause of airplane accidents involving the loss of life, causing over 9,000 deaths since the beginning of the commercial jet aircraft. CFIT was identified as a cause of ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Automatic Direction Finder
An automatic direction finder (ADF) is a marine or aircraft radio-navigation instrument that automatically and continuously displays the relative bearing from the ship or aircraft to a suitable radio station. ADF receivers are normally tuned to aviation or marine NDBs (Non-Directional Beacon) operating in the LW band between 190 – 535 kHz. Like RDF ( Radio Direction Finder) units, most ADF receivers can also receive medium wave (AM) broadcast stations, though as mentioned, these are less reliable for navigational purposes. The operator tunes the ADF receiver to the correct frequency and verifies the identity of the beacon by listening to the Morse code signal transmitted by the NDB. On marine ADF receivers, the motorized ferrite-bar antenna atop the unit (or remotely mounted on the masthead) would rotate and lock when reaching the null of the desired station. A centerline on the antenna unit moving atop a compass rose indicated in degrees the bearing of the station. On ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Airliner Accidents And Incidents In California
An airliner is a type of aircraft for transporting passengers and air cargo. Such aircraft are most often operated by airlines. Although the definition of an airliner can vary from country to country, an airliner is typically defined as an airplane intended for carrying multiple passengers or cargo in commercial service. The largest of them are wide-body jets which are also called twin-aisle because they generally have two separate aisles running from the front to the back of the passenger cabin. These are usually used for long-haul flights between airline hubs and major cities. A smaller, more common class of airliners is the narrow-body or single-aisle. These are generally used for short to medium-distance flights with fewer passengers than their wide-body counterparts. Regional airliners typically seat fewer than 100 passengers and may be powered by turbofans or turboprops. These airliners are the non- mainline counterparts to the larger aircraft operated by the major carri ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Accidents And Incidents Involving The Douglas DC-6
An accident is an unintended, normally unwanted event that was not directly caused by humans. The term ''accident'' implies that nobody should be blamed, but the event may have been caused by unrecognized or unaddressed risks. Most researchers who study unintentional injury avoid using the term ''accident'' and focus on factors that increase risk of severe injury and that reduce injury incidence and severity. For example, when a tree falls down during a wind storm, its fall may not have been caused by humans, but the tree's type, size, health, location, or improper maintenance may have contributed to the result. Most car wrecks are not true accidents; however English speakers started using that word in the mid-20th century as a result of media manipulation by the US automobile industry. Types Physical and non-physical Physical examples of accidents include unintended motor vehicle collisions, falls, being injured by touching something sharp or hot, or bumping into someth ...

Disasters In California
A disaster is a serious problem occurring over a short or long period of time that causes widespread human, material, economic or environmental loss which exceeds the ability of the affected community or society to cope using its own resources. Disasters are routinely divided into either "Natural disaster, natural disasters" caused by Natural hazard, natural hazards or "human-instigated disasters" caused from Anthropogenic hazard, anthropogenic hazards. However, in modern times, the divide between natural, human-made and human-accelerated disasters is difficult to draw. Examples of natural hazards include avalanche, avalanches, Flood, flooding, cold wave, cold waves and heat wave, heat waves, drought, droughts, earthquake, earthquakes, Cyclone, cyclones, landslide, landslides, lightning, tsunami, tsunamis, Volcanism, volcanic activity, wildfire, wildfires, and Winter storm, winter precipitation. Examples of anthropogenic hazards include Crime, criminality, civil disorder, terr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Aviation Accidents And Incidents In The United States In 1951
Aviation includes the activities surrounding mechanical flight and the aircraft industry. ''Aircraft'' includes fixed-wing and rotary-wing types, morphable wings, wing-less lifting bodies, as well as lighter-than-air craft such as hot air balloons and airships. Aviation began in the 18th century with the development of the hot air balloon, an apparatus capable of atmospheric displacement through buoyancy. Some of the most significant advancements in aviation technology came with the controlled gliding flying of Otto Lilienthal in 1896; then a large step in significance came with the construction of the first powered airplane by the Wright brothers in the early 1900s. Since that time, aviation has been technologically revolutionized by the introduction of the jet which permitted a major form of transport throughout the world. Etymology The word ''aviation'' was coined by the French writer and former naval officer Gabriel La Landelle in 1863. He derived the term from the v ...
