That is truly scary.
Judging by the length of the takeoff roll and that they touched down then became airborne again after takeoff, it looks very much like a performance (lack of) related accident. They were barely out of ground effect for much of the 'flight'.
Maybe high density altitude as well, by the look of the vegetation? The ground seems to be subtly rising as they fly into it, as well.
Plenty of opportunity to call it a day while they still had grass underneath. Good that they didn't try any turns, though...
