A pilot is safe after ejecting from an F-35 fighter jet that crashed at Eielson Air Force Base in Alaska, officials said.

A F-35 fighter jet was destroyed after it went up in flames following a crash at a US airbase. Footage shows when the military jet fell from the sky during a routine exercise at the Eielson Air Force Base in Alaska. The pilot managed to escape just moments before the jet began spiralling down yesterday afternoon.
