A JASDF F-15 (304th Squadron, 8th Air wing, based in Chikujo, Fukuoka Prefecture) has crashed into the Sea of Japan about 30km south west of Mishima island, Yamaguchi prefecture.
The pilot, 2nd lieutenant Soichiro Murakami, successfully ejected and was later rescued.
According to the air self defence force, the aircraft took off at 15:43 and was taking part in training exercises with 6 other F-15s when trouble developed in both engines at around the same time leading to loss of power. Attempts to restart the engines were unsuccessful and the pilot, losing control of the aircraft ejected at 800m.
The investigation is already underway. They are also looking into the feasibility of recovering the crashed aircraft from the sea.
