The 'widening of the track' has occured after the aircraft jumped and dropped down a significant embankment adjacent to the taxyway. Note the summer picture of the site as compared to the accident photo above. Therefore I believe the widening of the track is in fact both engines contacting the ground after this drop. The aircraft then crossed a small gully and has come to rest on the upslope opposite. I don't believe the apparent wider wheel track has been caused by the wheels, although the undercarriage clearly collapsed during the accident, I think it happened after this drop.
