The flight was 10 hours and 23 minutes, according to FlightAware, a flight tracking service. The 777 is a smaller, wide-body jet that can travel long distances without refueling and is typically used for long flights over water.

The most notable accident involving a 777 occurred on Jan. 17, 2008 at Heathrow Airport in London. British Airways Flight 28 landed hard about 1,000 feet short of the runway and slid onto the start of the runway. The impact broke the 777-200’s landing gear. There were 47 injuries, but no fatalities.

An investigation revealed ice pellets that had formed in the fuel were clogging the fuel-oil heat exchanger, blocking fuel from reaching the plane’s engines. The Rolls-Royce Trent 800 series engines that were used on the plane were then redesigned.

Bill Waldock, an expert on aviation accident investigation, said he was reminded of the Heathrow accident as he watched video of Saturday’s crash. “Of course, there is no indication directly that’s what happened here,” he said. “That’s what the investigation is going to have to find out.”

The Asiana 777 “was right at the landing phase and for whatever reason the landing went wrong,” said Waldock, director of the Embry-Riddle University accident investigation laboratory in Prescott, Ariz. “For whatever reason, they appeared to go low on approach and then the airplane pitched up suddenly to an extreme attitude, which could have been the pilots trying to keep it out of the ground.”

The last time a large U.S. airline lost a plane in a fatal crash was an American Airlines Airbus A300 taking off from John F. Kennedy International Airport in New York in 2001.

Smaller airlines have had crashes since then. The last fatal U.S. crash was a Continental Express flight operated by Colgan Air, which crashed into a house near Buffalo, N.Y. on Feb. 12, 2009. The crash killed all 49 people on board and one man in a house.

Flying remains one of the safest forms of transportation: There are about two deaths worldwide for every 100 million passengers on commercial flights, according to an Associated Press analysis of government accident data.

Just a decade ago, passengers were 10 times as likely to die when flying on an American plane. The risk of death was even greater during the start of the jet age, with 1,696 people dying — 133 out of every 100 million passengers — from 1962 to 1971. The figures exclude acts of terrorism.

Asia remains one of the fastest-growing regions for aviation in the world. Even with slowing economies in Japan and China, airlines there saw 3.7 percent more passengers than a year ago, according to the International Air Transport Association.

Finding enough experienced pilots to meet a growing number of flights is becoming a problem. A 2012 report by aircraft manufacturer Boeing said the industry would need 460,000 new commercial airline pilots in the next two decades — with 185,000 of them needed in Asia alone.

“The Asia-Pacific region continues to present the largest projected growth in pilot demand,” the report said.
