- A plane carrying 181 people crashed at an airport in South Korea on Sunday, killing 179.
- Photos and videos show the aircraft overrunning a runway before being engulfed in flames.
- It will likely take months or years to uncover why the plane crashed.
A commercial aircraft crashed at a South Korean airport on Sunday, killing 179 people, according to officials.
Flight 7C2216, operated by the Korean budget airline Jeju Air, was carrying 181 passengers and crew when it tried to land at Muan International Airport at 9:03 a.m. local time, but veered off the runway, per the Associated Press.
A video broadcast by MBC News, a South Korean news network, showed the plane speeding down the runway, with smoke coming from its belly, before it crashed into what appeared to be a barrier and burst into flames.
The flight was traveling from Suvarnabhumi International Airport, Bangkok.
The aircraft was a 15-year old Boeing 737-800 that Ryanair, a budget Irish airline, operated before it was delivered to Jeju Air in 2017, according to the Planespotters.net flight tracking website. It was not a Max variant, which has been embroiled in quality and production problems.
The plane tried to touch down "without its landing gear extended," the tracker said.
In a statement to Business Insider, Boeing gave its condolences to families who lost loved ones and said it was in contact with and "ready to support" Jeju Air. Spokespeople for Jeju Air did not immediately respond to a request for comment.
A total of 179 people died, the National Fire Agency said per AP: 85 women, 84 men, and 10 others whose gender was not immediately identifiable.
Authorities said they were working closely with bereaved families to identify the deceased and make plans to transfer their bodies. A temporary morgue was set up at the airport.
Two of the plane's six crew members survived and were conscious, according to local health officials.
A male was transported to a hospital, while a female was initially admitted to a separate facility and was scheduled to be transferred to a medical center, according to the transport ministry.
Over 1,500 personnel were mobilized, including 490 from the fire department, 455 police, and 340 from the military, according to the transport police.
In a statement posted online, Jeju Air said that it was "bowing" its head in apology and would address the crash.
This is the first fatal crash involving a Jeju plane since it was founded in 2005. Airline News editor Geoffrey Thomas told CNN the crash is "perplexing" because South Korea and the 737 model involved both have historically high safety records.
The last major aviation accident involving a South Korean airline was in 1997 when a Korean Air jet crashed in Guam, killing 228 people.
Reports of birds striking the aircraft
Lee Jeong-hyeon, chief of the Muan fire station, said in a televised briefing that workers were investigating what caused the crash, including whether the aircraft was struck by birds.
He said the plane was almost completely destroyed, with the tail assembly the most intact part of the wreckage.
Officials said that air traffic controllers warned about bird strike risks minutes before the incident, and a surviving crew member mentioned a bird strike after being rescued, The Guardian reported.
Per South Korea's Yonhap News Agency, Muan International Airport has the highest rate of bird strike incidents among 14 airports nationwide.
Keith Tonkin, the managing director of Aviation Projects, an aviation consulting company in Australia, told Business Insider: "it appears that the aircraft wasn't configured for a normal landing — the landing gear wasn't down and it looks like the wing flaps weren't extended either.
"It also seems as though the landing was rushed — there aren't any reports of the aircraft circling to prepare for the emergency landing, which is what you would do if were aware that the landing gear or flaps couldn't be extended."
Black boxes recovered
The Independent reported that transport ministry officials said they recovered the aircraft's two black boxes: the flight data recorder and the cockpit voice recorder.
These provide investigators with an abundance of information that helps string together the sequence of events before and during a crash and determine what happened.
Despite speculation, Air crash investigations can take months or years to complete, meaning the cause of the crash likely won't be known for a long time.
And they typically have more than one cause — known as the "Swiss Cheese Model" in aviation, a string of smaller errors often leads to an accident, not just one.
"The biggest risk is speculation because it obscures the actual causes of a near-miss, incident, or accident," Simon Bennett, aviation safety expert at the University of Leicester, UK, told BI.
"I appreciate that the relatives of the dead and injured will want answers. Understandably, they will want closure," he said. "However, rushing the investigation would do a huge disservice to the aviation community and airlines' customers."
The crash occurred amid a political crisis in South Korea and two days into the tenure of acting president Choi Sang-mok.
Choi took over from the country's previous acting president, Han Duck-soo, who was impeached two weeks after succeeding president Yoon Suk Yeol, who was himself impeached after trying to impose martial law.
