Aviation, or air transport, refers to the activities surrounding mechanical flight and the aircraft industry. Aircraft includes fixed-wing and rotary-wing types, morphable wings, wing-less lifting bodies, parachutes, as well as lighter-than-air craft such as 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; then a largest 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 with the introduction of the jet which permitted a major form of transport throughout the world.

Mirabel Satellite photo
Montréal-Mirabel International Airport is a large airport located in Mirabel, Quebec, near Montreal and was opened 4 October 1975. The airport serves mainly cargo flights, and is a manufacturing base of Bombardier Aerospace, where final assembly of regional jets (CRJ700 and CRJ900) aircraft is conducted. It is part of the National Airports System. It is the second largest airport in the world in terms of area, covering more land area than the five New York City boroughs.

The airport's location and lack of transport links, as well as Montreal's economic decline relative to Toronto, made it unpopular with airlines. Eventually relegated to the simple role of a cargo airport, Mirabel became an embarrassment widely regarded in Canada as being a boondoggle, or a "white elephant," and one of the best examples of a failed megaproject.

Singapore Airlines B773 9V-SWA.jpg

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 October 2009, 56 customers have placed orders for 1,116 aircraft of all variants, with 822 delivered. The most common variant used worldwide is the 777-200ER, with 412 aircraft delivered, and Emirates operates the largest 777 fleet, with 78 aircraft. The airliner has had one hull-loss accident, with no passenger fatalities, attributed to a Trent 800 engine fuel component as of October 2009.

Through the 2000s, 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 and the A340, with the upcoming A350 XWB and Boeing 787 programs currently in development.

Selected biography

Frank Whittle speaking to employees of the Flight Propulsion Research Laboratory (now known as the NASA Glenn Research Center), USA, in 1946
Air Commodore Sir Frank Whittle (1 June 1907 – 9 August 1996) was a Royal Air Force officer and was one of the inventors of jet propulsion. By the end of the war, Whittle's efforts resulted in engines that would lead the world in performance through the end of the decade.

Born in Earlsdon, Coventry, England on June 1, 1907, Whittle left Leamington College in 1923 to join the Royal Air Force (RAF). Through his early days as an Aircraft apprentice he maintained his interest in the Model Aircraft Society where he built replicas, the quality of which attracted the eye of his commanding officer, who was so impressed that he recommended Whittle for the Officer Training College at Cranwell in Lincolnshire in 1926, a rarity for a "commoner" in what was still a very class-based military structure. A requirement of the course was that each student had to produce a thesis for graduation. Whittle decided to write his thesis on future developments in aircraft design, in which he described what is today referred to as a motorjet.

Whittle and Hans von Ohain met after the war and initially Whittle was angry with him as he felt Ohain had stolen his ideas. Ohain eventually convinced him that his work was independent and after that point the two became good friends.

  • 1964 – US Navy aircraft attack North Vietnamese naval bases, spearheading direct US involvement in the Vietnam War.
  • 1954 – As the first pre-production Douglas A2D-1 Skyshark, BuNo 125480, piloted by George Jansen, is flown on a test flight out of Edwards AFB, California, the temperamental gearbox transferring the Allison XT-40A power to counter-rotating propellers fails, and even though the powerplant continues to partially function, the props automatically feather. Unable to spot a reasonable landing spot, the pilot ejects, suffering back injuries that leave him a plaster cast for several months. The Skyshark program is cancelled one month later, with only six of ten pre-production A2D-1s completed ever being flown.
  • 1952 – Convair B-36D-25-CF Peacemaker, 49-2661, c/n 121, on bailment to Convair, San Diego, California, crashes into San Diego Bay at 1430 PDT, while on a normal shakedown flight following completion of "San-San" project modification. The number 5 engine catches fire in flight and then falls off the wing. The aircraft is destroyed by impact and explosion. Four of the eight crewmembers, all Convair flight test employees, receive minor injuries, two are uninjured, and two are lost, first flight engineer W. W. Hoffman, by drowning, while the pilot, David H. Franks, 40, stays with the plane to manoeuvre it out to sea and away from occupied land. His body is never found. Coast Guard planes rescue four and Navy ships pick up two. The rescued, none seriously injured, are R. W. Adkins, co-pilot; Kenneth Rogers, flight engineer, W. F. Ashmore, Roy E. Sommers, D. R. Maxion and W. E. Wilson, all of San Diego. The UB88 Project dive team determined that the bomber actually came down in the Pacific off of Mission Beach.

The crew attempts an emergency landing but crashes, causing a huge explosion that kills 19 aboard the plane and on the ground, including mission commander Brig. Gen. Robert F. Travis; the airfield is later renamed Travis Air Force Base in his honor. Numerous nearby mobile homes are severely damaged and many civilians, firefighters, and USAF ground crew are injured- 60 required hospital treatment and 47 suffered superficial injuries according to newspaper reports, but other sources place the total as high as 173. The USAF attributes the explosion to ten or twelve conventional 500-pound HE bombs aboard the B-29 and claims that the nuclear bomb's fuel capsule was aboard a different aircraft, but admits that the bomb casing contained depleted uranium used as ballast, and later orders a public health assessment of the crash site.
