It sure looks like the pilot was taking off from a high-density
altitude airport with no flaps, downwind.

From this link I would not say that it was a high DA airport.

Downwind? I just could not tell from the vegetation moving and I
never saw a windsock.

It did appear as though he was rapidly approaching the end of pavement
and may have lifted off with minimal airspeed. Note the wings soon
after liftoff and then right before the impact with terrain.

Shouldn't 4000' be enough at that elevation for that aircraft?
