Hong Kong (CNN)A Japanese F-35 fighter crashed into the Pacific Ocean on Tuesday, raising questions about reliability and security of the most expensive weapons system ever made.
The stealth jet disappeared from radar minutes into a training mission from Misawa Air Base in northern Japan. Defense officials said its pilot signaled the need to abort the mission shortly before the plane was lost.
Japanese Defense Minister Takeshi Iwaya said debris from the plane, parts of its two tail fins, was found early Wednesday.
