An Air Force pilot is safe after ejecting out of an F-35 fighter jet that then crashed at the Eielson Air Force Base in Alaska.

This marks the 11th F-35 crash since 2018, adding to concerns over the jet’s reliability. The aircraft, developed by Lockheed Martin, has faced multiple technical failures, including crashes in New Mexico,

The pilot declared an emergency and ejected before the plane went down Tuesday afternoon, military officials said.
