A Boeing 747

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. (Full article...)

Hot air balloon
Hot air balloon
The hot air balloon is the oldest successful human-carrying flight technology. On November 21, 1783, in Paris, France, the first manned flight was made by Jean-François Pilâtre de Rozier and François Laurent d'Arlandes in a hot air balloon created by the Montgolfier brothers.

A hot air balloon consists of a bag called the envelope that is capable of containing heated air. Suspended beneath is the gondola or wicker basket (in some long-distance or high-altitude balloons, a capsule) which carries the passengers and a source of heat. The heated air inside the envelope makes it buoyant since it has a lower density than the relatively cold air outside the envelope. Unlike gas balloons, the envelope does not have to be sealed at the bottom since the air near the bottom of the envelope is at the same pressure as the surrounding air. In today's sport balloons the envelope is generally made from nylon fabric and the mouth of the balloon (closest to the burner flame) is made from fire resistant material such as Nomex.

Recently, balloon envelopes have been made in all kinds of shapes, such as hot dogs, rocket ships, and the shapes of commercial products. Hot air balloons that can be propelled through the air rather than just being pushed along by the wind are known as airships or, more specifically, thermal airships. (Full article...)

Selected biography

Benjamin Delahauf Foulois (1879-1967) was an early aviation pioneer who rose to become a chief of the U.S. Army Air Corps. The son of a French immigrant, he was born and raised in Connecticut. He enlisted in the Army at age 18 to serve in the Spanish–American War. After just a few month he was separated because of disease he had picked up in Puerto Rico. He re-enlisted in 1899 and was sent to the Philippines where he received a commission as a Second Lieutenant. Foulois believed that the new airplane would replace the cavalry for reconnaissance and in 1908 transferred into the Signal Corps.

Foulois conducted the acceptance test for the Army's first aircraft, a Wright Model A, in 1909. He participated in the Mexican Expedition from 1916–17 and was part of the American Expeditionary Force in France during World War I where he was responsible for the logistics and maintenance of the U.S. air fleet. During World War I he and Billy Mitchell began a long and hostile relationship over the direction of military aviation and the best method to get there. After the war he served as a military attaché to Germany where he gathered a great deal of intelligence on German aviation. He later went on to command the 1st Aero Squadron and ultimately commanded the Air Corps.

He retired in 1935 as part of the fallout from the Air Mail scandal. Foulois continued to advocate for a strong air service in retirement. In 1959, at the invitation of the Chief of Staff of the Air Force, Foulois began touring Air Force bases advocating national security. He died of a heart attack on 25 April 1967 and is buried in his home town of Washington, Connecticut.

Selected Aircraft

The Boeing 777 is a long-range, wide-body twin-engine jet airliner manufactured by Boeing Commercial Airplanes. It is the world's largest twinjet and is commonly referred to as the "Triple Seven". The aircraft has seating for over 300 passengers and has a range from 5,235 to 9,380 nautical miles (9,695 to 17,372 km) depending on model. Its distinguishing features include the largest diameter turbofan engines of any aircraft, six wheels on each main landing gear, a circular fuselage cross-section, and blade-shaped tail cone. Developed in consultation with eight major airlines, the 777 was designed to replace older wide-body airliners and bridge the capacity difference between the 767 and 747. As Boeing's first fly-by-wire airliner, it has computer mediated controls; it is also the first entirely computer-designed commercial aircraft.

The 777 is produced in two fuselage lengths. The original 777-200 model first entered service in 1995, followed by the extended range 777-200ER in 1997; the stretched 777-300, which is 33.3 ft (10.1 m) longer, began service in 1998. The longer-range 777-300ER and 777-200LR variants entered service in 2004 and 2006, respectively, while a freighter version, the 777F, debuted in 2008. Both longer-range versions and the freighter feature General Electric GE90 engines, as well as extended and raked wingtips. Other models are equipped with either the GE90, Pratt & Whitney PW4000, or Rolls-Royce Trent 800 engines. The 777-200LR ranks as the world's longest-range airliner and holds the record for longest distance flown by an unrefuelled commercial aircraft, with the demonstrated capability to fly more than halfway around the world.

United Airlines first placed the 777 into commercial airline service in 1995. As of August 2023, 1,716 777s have been delivered. The most common variant used worldwide is the 777-300ER, with 832 aircraft delivered, and Emirates operates the largest 777 fleet, with 134 aircraft (as of May 2019). The airliner has had 8 hull-loss accidents, with 541 fatalities. The most deadly incident was Malaysia Airlines Flight 17, in which a 777-200ER carrying 298 people was shot down by a missile over Ukraine on 17 July 2014.

Through the 21st century, the 777 has emerged as one of its manufacturer's best-selling models. Because of rising fuel costs, airlines have acquired the type as a comparatively fuel-efficient alternative to other wide-body jets and have increasingly used the aircraft on long-haul, transoceanic routes. Direct market competitors include the Airbus A330-300, the A340 and A350 XWB.

The airplane floated for ten days and was sunk by USS Wisconsin.
  • 1957 – 1st Lt. David Steeves departs Hamilton AFB, California for Craig AFB, Alabama, in T-33A-1-LO Shooting Star, 52-9232, and disappears without a trace. Declared dead by the Air Force, he emerges from the Kings Canyon National Park in the Sierra Nevada mountains 54 days later, having ejected from the jet after an in-flight emergency. He stumbled on a ranger cabin during his ordeal where he found fish hooks, a canned ham and a can of beans. Unable to locate the downed trainer, officials eye him with suspicion and rumors that he traded to jet to the Russians, or flew it to Mexico, dog the pilot and ruin his military career. He returns to civilian life and eventually dies in an aircraft accident in 1965. Finally, in 1977, Boy Scouts hiking in the national park discover the canopy of his T-33, too late to vindicate the pilot's story and reputation.
  • 1952 – French Leduc 0.16 research ramjet again suffers landing gear collapse on touchdown and is damaged. After several more flights in 1954, it will be retired to the Musée de l'Air.

Robert Gray depart from Fort Kamehameha in a Curtiss N-9 of the 6th Aero Squadron, make a stop in Maui, and then continue to the island of Hawaii. Clark encounters fog and darkness over the island, causing him to crash in the jungle near Hilo. Two days after the crash, Clark and Gray emerge from the Hawaiian jungle unhurt. According to Harold Richards in "The History of Army Aviation in Hawaii", Clark accomplished another "first" on this flight as he had agreed to deliver two letters from Oahu residents to their relatives on Hawaii. After emerging from the jungle, Clark delivers the letters to their intended recipients. Thus, Clark carried the first letters by airmail in the Hawaiian Islands.
