A US Air Force fighter jet crashed during a training exercise at Eielson Air Force Base in Alaska on Tuesday. The pilot flying the single-seat F-35 fighter was safe after bailing out. A video of the crash was widely posted on social media, where the aircraft can be seen vertically descending from the air and flipping before it crashed. The crash was followed by a large explosion, with fire rising several meters up in the air. The pilot, who ejected the plane on time, was seen descending on the ground with the help of a parachute. The pilot experienced an "in-flight malfunction," and was able to eject from the aircraft, US Air Force Colonel Paul Townsend, commander of the 354th Fighter Wing, told a news conference, according to a report from the Associated Press.
