Montréal-Mirabel International Airport
is a large airport located in Mirabel
, 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.

Thirteen C-17 Globemaster III aircraft fly over the Blue Ridge Mountains in Virginia during low level tactical training Dec. 20, 2005. The C-17s, assigned to the 437th and 315th Airlift Wings at Charleston Air Force Base, S.C., demonstrated the strategic airdrop capability of the U.S. Air Force.
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.
