Mauersegler,
Good work (which implies a theory of things gone wrong after the downwind). Check out this picture from a Turkish newspaper, indicating another direction of impact if I interpret it correctly
"Pist" stands for runway, the clipped blue arrow to the right said "lake" in the original newspaper story.
Your pin #1 may be correct, but #2 may have to be on the opposite side of the ridge. On Google Earth, I have also tried to locate the white building on the top of the ridge visible on many news photos without finding it.
