F-35 fighter jet crashes in Alaska.

[Zaphod58]

Well, two things are clear, the aircraft wasn't travelling horizontally with great speed, and it was quite low to the ground given the appearance of the pilot, under parachute, shortly after the really expensive aircraft pancaked itself.

It was a flight of two arriving back at Eielson. The second aircraft an be seen at the start of the video. That means he was either in the break, and turning at the time, or had just come out of the break when it happened.
