Twenty-two of the 36 people aboard the aircraft, including one crewmember,} perished in the evening crash on Easter Sunday.

On this particular flight, the first officer was in the left seat, as he was being line-checked by the captain; both pilots survived. Takeoff and crash As the aircraft became airborne from runway 23 (since removed), a sharp yaw was experienced while the first officer reduced power at an altitude of approximately . Almost immediately, the fire warning light for the number one engine illuminated; however, the fire warning bell never sounded. At this point, the first officer is thought to have throttled dow ...

Moon Township, Allegheny County, Pennsylvania
Moon Township is a township along the Ohio River in Allegheny County, Pennsylvania. Moon is a part of the Greater Pittsburgh metropolitan area and is located northwest of Pittsburgh. The population was 27,261 at the 2020 census. History Early history (1756–1773) The initial settlement of Moon Township was a direct result of the westward expansion of English settlers and traders who arrived in the Ohio Valley in the early to mid-18th century. During the French and Indian War (Seven Years' War), the Iroquois, who controlled the land for hunting grounds through right of conquest, ceded large parcels of southwestern Pennsylvania lands through treaty or abandonment to settlers. In some cases, the land was already occupied by squatters who were to be forced off the land. In the face of this turmoil, Native American settlements of the south bank of the Ohio River typically relocated to more populous areas of the north bank in the current locales of Sewickley and Ambridge.

Propeller (aeronautics)
An aircraft propeller, also called an airscrew,Beaumont, R.A.; ''Aeronautical Engineering'', Odhams, 1942, Chapter 13, "Airscrews". converts rotary motion from an engine or other power source into a swirling slipstream which pushes the propeller forwards or backwards. It comprises a rotating power-driven hub, to which are attached several radial airfoil-section blades such that the whole assembly rotates about a longitudinal axis. The blade pitch may be fixed, manually variable to a few set positions, or of the automatically variable "constant-speed" type. The propeller attaches to the power source's driveshaft either directly or through reduction gearing. Propellers can be made from wood, metal or composite materials. Propellers are most suitable for use at subsonic airspeeds generally below about , although supersonic speeds were achieved in the McDonnell XF-88B experimental propeller-equipped aircraft. Supersonic tip-speeds are used in some aircraft like the Tupolev Tu-95, wh ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Airliner Accidents And Incidents In Pennsylvania
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 carr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Accidents And Incidents Involving The Martin 4-0-4
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 some ...

Aviation Accidents And Incidents In The United States In 1956
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 th ...
