TOKYO -- The pilot of a Lockheed Martin F-35A stealth fighter jet that crashed into the Pacific Ocean called an end to his training exercise just before the plane went down, it was learned Wednesday.
Japan's Defense Ministry has launched an investigation to determine the cause of Tuesday's crash, which will be carried out by the ministry's aircraft accident investigation commission. The Japan Air Self-Defense Force has requested the U.S. military's cooperation for the probe as well.
