Albert Hickman (pilot)
The 1959 San Diego F3H crash was the crash of a United States Navy McDonnell F3H-2N Demon in San Diego, California, on 4 December 1959. The pilot, Ensign Albert Joseph Hickman from VF-121, chose not to eject from the stricken aircraft, piloting it away from populated areas of Clairemont, including an elementary school, saving "as many as 700 people" on the ground, according to one estimate. The aircraft crashed into a canyon, with the pilot being the sole fatality. Hickman has been memorialized in the naming of an elementary school and a sports complex in San Diego. Several decades later, a similar crash occurred in University City, a neighborhood north of Clairemont. Background Pilot Albert Joseph Hickman was born in Sioux City, Iowa, on April 4, 1938. Later he graduated from Central High School in 1956, enlisting in the Navy before graduating. Hickman was a naval aviator, being assigned to VF-121, a training squadron at Naval Air Station Miramar.

Clairemont, San Diego
Clairemont (or Clairemont Mesa) is a community within the city of San Diego, California, United States. It has a population of about 81,600 residents and an area of roughly . Clairemont Mesa is bordered by Interstate 805 on the east, Interstate 5 to the west, State Route 52 to the north, and the community of Linda Vista to the south. The community of Clairemont Mesa can be subdivided into the neighborhoods of North Clairemont, Clairemont Mesa East, Clairemont Mesa West, Bay Park, and Bay Ho. History Prior to in-migration by Europeans, the area was populated by the Kumeyaay people. The Spanish arrived in 1542 and founded Mission Basilica San Diego de Alcalá nearby in 1769. Judge Hyde was one of the first settlers of Clairemont and began farming in Tecolote Canyon in 1872. Farming and ranching continued in the area until World War II. In 1887 the Morena Subdivision was mapped. The subdivision was bounded by streets that are known today as Morena Boulevard on the west, Milto ...

Mission San Diego De Alcalá
Mission Basilica San Diego de Alcalá ( es, Misión San Diego de Alcalá) was the second Franciscan founded mission in The Californias (after San Fernando de Velicata), a province of New Spain. Located in present-day San Diego, California, it was founded on July 16, 1769, by Spanish friar Junípero Serra in an area long inhabited by the Kumeyaay people. The mission and the surrounding area were named for the Catholic saint Didacus of Alcalá, a Spaniard more commonly known as ''San Diego''. The mission was the site of the first Christian burial in Alta California. The original mission burned in 1775 during an uprising by local natives. San Diego is also generally regarded as the site of the region's first public execution, in 1778. Father Luis Jayme, California's first Christian martyr who was among those killed during the 1775 uprising against the mission, lies entombed beneath the chancel floor. The current church, built in the early 19th century, is the fifth to stand on th ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Chaparral
Chaparral ( ) is a shrubland plant community and geographical feature found primarily in the U.S. state of California, in southern Oregon, and in the northern portion of the Baja California Peninsula in Mexico. It is shaped by a Mediterranean climate (mild wet winters and hot dry summers) and infrequent, high-intensity crown fires. Chaparral features summer-drought-tolerant plants with hard sclerophyllous evergreen leaves, as contrasted with the associated soft-leaved, drought-deciduous, scrub community of coastal sage scrub, found often on drier, southern facing slopes within the chaparral biome. Three other closely related chaparral shrubland systems occur in central Arizona, western Texas, and along the eastern side of central Mexico's mountain chains (mexical), all having summer rains in contrast to the Mediterranean climate of other chaparral formations. Chaparral comprises 9% of California's wildland vegetation and contains 20% of its plant species. The name comes fro ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
San Clemente Canyon
San Clemente Canyon is a canyon located in the city of San Diego, in San Diego County, California.Marian Bear Memorial Park, a linear open space park, is along the canyon and in the southern tributary arroyos and mesa. Park The canyon and Marian Bear Memorial Park parallels the San Clemente Canyon Freeway (State Route 52) (along northern canyon slopes), between its junctions with Interstate 5 (on west) and Interstate 805 (on east) at the ends. The park provides a natural setting in the midst of a busy urban area. The of dedicated natural parkland include finger canyons and mesas on the south side. The main canyon and its tributaries continue to support a population of resident wildlife including raccoons, skunks, rabbits, amphibians, reptiles, and birds, and serve as a pathway for coyote, fox, and other native mammals. Along the length of the canyon are coast live oak, California sycamore, and native willow tree woodlands, with an undergrowth of native and other plant species ...

Aircraft Canopy
An aircraft canopy is the transparent enclosure over the cockpit of some types of aircraft. An aircraft canopy provides a controlled and sometimes pressurized environment for the aircraft's occupants, and allows for a greater field of view over a traditional flight deck. A canopy's shape is a compromise designed to minimize aerodynamic drag, while maximizing visibility for pilots and other crewmembers. History Very early aircraft had no canopies. The pilots were exposed to the wind and weather, although most flying was done in good weather. Through World War I most aircraft had no canopy, although they often had a small windshield to deflect the prop wash and wind from hitting the pilot in the face. In the 1920s and 1930s, the increasing speed and altitude of airplanes necessitated a fully enclosed cockpit and canopies became more common. Early canopies were made of numerous pieces of flat glass held in position by a frame and muntins. The muntins reduced visibility, which ...

Ejection Seat
In aircraft, an ejection seat or ejector seat is a system designed to rescue the pilot or other crew of an aircraft (usually military) in an emergency. In most designs, the seat is propelled out of the aircraft by an explosive charge or rocket motor, carrying the pilot with it. The concept of an ejectable escape crew capsule has also been tried. Once clear of the aircraft, the ejection seat deploys a parachute. Ejection seats are common on certain types of military aircraft. History A bungee-assisted escape from an aircraft took place in 1910. In 1916, Everard Calthrop, an early inventor of parachutes, patented an ejector seat using compressed air. The modern layout for an ejection seat was first introduced by Romanian inventor Anastase Dragomir in the late 1920s. The design featured a ''parachuted cell'' (a dischargeable chair from an aircraft or other vehicle). It was successfully tested on 25 August 1929 at the Paris-Orly Airport near Paris and in October 1929 a ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Compressor Stall
A compressor stall is a local disruption of the airflow in the compressor of a gas turbine or turbocharger. A stall that results in the complete disruption of the airflow through the compressor is referred to as a compressor surge. The severity of the phenomenon ranges from a momentary power drop barely registered by the engine instruments to a complete loss of compression in case of a surge, requiring adjustments in the fuel flow to recover normal operation. Compressor stall was a common problem on early jet engines with simple aerodynamics and manual or mechanical fuel control units, but has been virtually eliminated by better design and the use of hydromechanical and electronic control systems such as Full Authority Digital Engine Control. Modern compressors are carefully designed and controlled to avoid or limit stall within an engine's operating range. Types There are two types of compressor stall: Rotating stall Rotating stall is a local disruption of airflow within the c ...

McDonnell F3H-2N Demon
The McDonnell F3H Demon is a subsonic swept-wing United States Navy carrier-based jet fighter aircraft. The successor to the F2H Banshee, the Demon was originally designed to use the Westinghouse J40 engine, but had to be redesigned to accept the Allison J71 after the J40 suffered severe problems and was ultimately abandoned.Angelucci and Bowers 1987, p. 304. Though it lacked sufficient power for supersonic performance, it complemented day fighters such as the Vought F8U Crusader and Grumman F11F Tiger as an all-weather, missile-armed interceptor until 1964. It was withdrawn before it could serve in Vietnam when both it and the Crusader were replaced on ''Forrestal''-class and similar supercarriers by the McDonnell Douglas F-4 Phantom II. McDonnell's Phantom, which was equally capable against ground, fighter, and bomber targets, bears a strong family resemblance, as it was conceived as an advanced development of the Demon.
