The Korean air force reports that one of its F-15K Slam Eagle fighter jet crashed into a  mountain on March 05, 2018 at 2:38pm, local time. The body of the pilot has been found. Recovery teams are still looking for the co-pilot, who most likely died in the incident too, says Reuters.

The reason of the crash is still being investigated. The plane was returning from an unspecified mission to its base known as K-2 in Daegu International Airport (TAE).

The crash site is located deep in the Yuhak mountains, near Chilgok, south of the country. A golf course is located nearby but neither property damage nor civil injuries were reported. The recovery party of about 600 people took over two hours to reach the site due to foggy weather, dense vegetation and difficult terrain.

The F-15K is an advanced version of the F-15E acquired by South Korea between 2005 and 2012. Some of its components were manufactured by Boeing in collaboration with Korean industries, including Korea Aerospace Industries and Samsung Techwin.

It was fitted with a better radar than the F-15E as well as an upgraded Tactical Electronic Warfare System (TEWS) renamed ALQ-135M. It also sports chaff and flares countermeasures, like the Israeli version F-15I Raam. All of the F-15K fleet is affected to Daegu air base in the 11th Fighter Wing of the Republic of Korea Air Force.
