This image illustrates the problem the pilot had flying in high density altitude conditions. It appears that the pitch attitude is about 17 degrees, while the aircraft is not gaining altitude. Even if the measurement here is off by a degree or two, it's obvious that the aircraft was flying just short of stall.

Note to self: if ever in a situation like this, land on the remaining runway; or land in the field before the trees; and try to crash as well as these guys did.
