The Globe and Mail reports in its Wednesday edition that U.S. investigators, including representatives from Boeing, on Tuesday examined the site of a plane crash that killed 179 people in South Korea while authorities were conducting safety inspections on all Boeing 737-800 aircraft operated by the country's airlines. An Associated Press dispatch to The Globe says that all but two of the 181 people aboard the Boeing 737-800 operated by South Korean budget airline Jeju Air died in Sunday's crash. Video showed the aircraft, without its landing gear deployed, crash-landed on its belly and overshot a runaway at South Korea's Muan airport before it slammed into a concrete fence and burst into flames. The plane was seen having engine trouble, and preliminary examinations also say the pilots received a bird strike warning from the ground control centre and issued a distress signal as well. Many experts, however, say the landing gear issue was likely the main cause of the crash. South Korean authorities are looking at maintenance and operation records during five days of safety checks. John Hansman, an aviation expert at MIT, said the crash was most likely the result of a problem with the plane's hydraulic control systems.
