The UK Ministry of Defence spokesperson's remark comes after Japanese Defence Minister Takeshi Iwaya confirmed earlier on Wednesday that one of their F-35A stealth fighter jets had crashed in the Pacific Ocean.
On Tuesday, an F-35A fighter jet disappeared from radars 135 kilometres (84 miles) east of the Misawa Air Base, located in the country's northern Aomori prefecture. The incident took place during a training flight involving four F-35A fighters. The pilot who was on board the aircraft is still missing, according to an Air Self-Defence Force (ASDF) spokesman cited earlier by Reuters.
