Transcontinental flight in the context of "McDonnell Douglas DC-10"

American Airlines Flight 11 was a domestic passenger flight that was hijacked by five al-Qaeda terrorists on the morning of September 11, 2001, as part of the September 11 attacks. The hijacked airliner was deliberately crashed into the North Tower of the World Trade Center complex in New York City, killing everyone aboard the flight and resulting in the deaths of more than one thousand people in the top 18 stories of the skyscraper in addition to causing the demise of numerous others below the trapped floors. The crash of Flight 11 stands as the deadliest of the four suicide attacks executed that morning in terms of both plane and ground fatalities, the single deadliest act of terrorism in human history and the deadliest plane crash of all time. The aircraft involved, a Boeing 767-200ER with 92 passengers and crew, was flying American Airlines' daily scheduled morning transcontinental service from Boston Logan International Airport in Massachusetts to Los Angeles International Airport in California.

The airplane left the runway at 07:59. Less than fifteen minutes after takeoff, the hijackers injured two flight attendants, murdered one passenger, and breached the cockpit while forcing the passengers and crew to the rear of the aircraft. The assailants attacked both pilots, allowing lead hijacker Mohamed Atta to take over the controls. Air traffic controllers suspected that the flight was in distress because the crew became non-responsive. They realized that the plane had been hijacked when Atta's announcement to the hostages was accidentally transmitted to air traffic control instead of through the aircraft's PA system. Also, two flight attendants were able to contact American Airlines and pass along information relevant to the situation, including casualties suffered by the crew and passengers.

American Airlines Flight 77 was a scheduled domestic transcontinental passenger flight from Dulles International Airport in Northern Virginia to Los Angeles International Airport in Los Angeles. The Boeing 757-200 aircraft serving the flight was hijacked by five al-Qaeda terrorists on the morning of September 11, 2001, as part of the September 11 attacks. The hijacked airliner was deliberately crashed into the Pentagon in Arlington County, Virginia, killing all 64 aboard and another 125 in the building.

Flight 77 became airborne at 08:20 ET. Thirty-one minutes after takeoff, the attackers stormed the cockpit and forced the passengers and crew to the rear of the cabin, threatening the hostages but initially sparing all of them. Lead hijacker Hani Hanjour assumed control of the aircraft after having undergone extensive flight training as part of his preparation for the attack. In the meantime, two people aboard discreetly made phone calls to family members and relayed information on the situation without the knowledge of their assailants.

The Boeing 707 is an early American long-range narrow-body airliner, the first jetliner developed and produced by Boeing Commercial Airplanes.Developed from the Boeing 367-80 prototype, the initial 707-120 first flew on December 20, 1957.Pan Am began regular 707 service on October 26, 1958.With versions produced until 1979, the 707 is a swept wing quadjet with podded engines. Its larger fuselage cross-section allowed six-abreast economy seating, retained in the later 720, 727, 737, and 757 models.

Although it was not the first commercial jetliner in service, the 707 was the first to be widespread, and is often credited with beginning the Jet Age. It dominated passenger air-transport in the 1960s, and remained common through the 1970s, on domestic, transcontinental, and transatlantic flights, as well as cargo and military applications. It established Boeing as a dominant airliner manufacturer with its 7x7 series.The initial, 145-foot-long (44 m) 707-120 was powered by Pratt & Whitney JT3C turbojet engines.The shortened, long-range 707-138 and the more powerful 707-220 entered service in 1959.The longer-range, heavier 707-300/400 series has larger wings and is stretched slightly by 8 feet (2.4 m).Powered by Pratt & Whitney JT4A turbojets, the 707-320 entered service in 1959, and the 707-420 with Rolls-Royce Conway turbofans in 1960.

John Herschel Glenn Jr. (July 18, 1921 – December 8, 2016) was an American Marine Corps aviator, astronaut, businessman, and politician. He was the third American in space and the first to orbit the Earth, circling it three times in 1962. Following his retirement from NASA, he served from 1974 to 1999 as a U.S. Senator from Ohio; in 1998, he flew into space again at the age of 77.

Before joining NASA, Glenn was a distinguished fighter pilot in World War II, the Chinese Civil War, and the Korean War. He shot down three MiG-15s and was awarded six Distinguished Flying Crosses and eighteen Air Medals. In 1957, he made the first supersonic transcontinental flight across the United States. His on-board camera took the first continuous, panoramic photograph of the United States.

Air Canada is the flag carrier and the largest airline of Canada, by size and passengers carried. Air Canada is headquartered in the borough of Saint-Laurent in the city of Montreal. The airline, founded in 1937, provides scheduled and charter air transport for passengers and cargo to 222 destinations worldwide. It operates major hubs at Montréal–Trudeau, Toronto–Pearson and Vancouver. Air Canada is a founding member of the Star Alliance.

Canada's national airline originated from the Canadian federal government's 1936 creation of Trans-Canada Air Lines (TCA), which began operating its first transcontinental flight routes in 1938. In 1965, TCA was renamed Air Canada following government approval. After the deregulation of the Canadian airline market in the 1980s, the airline was privatized in 1988. On 4 January 2000, Air Canada took over its largest rival, Canadian Airlines. In 2003, the airline filed for bankruptcy protection and in the following year emerged and reorganized under the holding company ACE Aviation Holdings. In 2019, Air Canada flew 51.5 million passengers. In October 2021, the Government of Canada acquired 6.4% of Air Canada in return for financial support to mitigate the impacts from the COVID-19 pandemic.
