SEOUL, Jan. 14 (Yonhap) -- South Korea's F-35A fighter jet made an emergency belly landing following a bird strike on its left engine intake earlier this month, the country's Air Force announced Friday, adding there will be a follow-up investigation on the exact cause of the incident.

It made public the results of a preliminary joint probe by South Korea and the United States into what led to the Jan. 4 case, which occurred on a runway at an air base in Seosan, 151 kilometers south of Seoul, with its pilot unharmed.

The Air Force added a team of U.S. experts will visit South Korea for an additional probe into technical details, including exactly why the aviation electronics system and landing gear of the aircraft did not work at that time...
