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.

An F-35 Lightning II crashed during a scheduled training event at Eielson Air Force Base in Alaska, causing a massive fireball and spreading debris not far from the fence line, a video verified as authentic by officials showed.

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