A Japanese F-15 fighter jet that went missing is believed to have crashed. Defence Minister Nobuo Kishi said that the military is searching for the two crew members who were on board. The fighter jet dropped off radar over the sea of Japan after taking off from Komatsu air base. A part of the jet was spotted floating in waters about 5 kilometres from the Komatsu base. The F-15 is Japan’s Air Self-Defence Force’s mainstay fighter jet.
