Thanks. If the wing tip clipped a tree it was because the plane was turning. Assuming it wasn't windy, but foggy as stated, good avionics should've calculated that the tip would hit the ground, and good avionics would've detected trees. As such, a sound would've gone off to warn the pilot not to turn, or stop half way through a turn.

I could be wrong, but the pilot had already tried several times to land, and he was flying manually, and probably a good pilot, and there may have been a freak tree in terms of height, but I reckon he just didn't have modern enough instruments to help him avoid the crash.

I'm sorry, but you seem to know little about avionics. There are no 'tree detectors'.

No sane pilot would try a turn at this altitude, and the pilot knew very well what the altitude was because he had just aborted a landing attempt. It wasn't a turn, it was likely a stall.
