So much for "Wouldn't have happened if there had been a flight engineer..."
The underside of stbd wing struck the stone hut a massive blow which must have removed the inner flap and possibly the gear too - no sign of it in the in-flight photo but that could just be the angle. A big dust and debris cloud appears above the wing right after the impact. I also see an exhaust smudge from No.s 1 and 2 but nothing from 3. Again, might be the light/angle but with the amount of stone that engine must have ingested I'd be surprised if it was playing any useful part by then. Certainly there were considerable exhaust flashes during the impact sequence apparently from 2 and/or 3 - can't tell which - indicating severe mechanical strife.
