Nice picture!
This incident is a clear example of rolling moment due to beta, AKA
"dihedral effect".
In the video (http://www.liveleak.com/view?i=ddb_1204404185) it can be seen
that the trouble started when the pilot decrabbed the aircraft to align it
to the runway, after being flying into the wind. This decrab puts the
aircraft in a sideslip (airflow comming from the side, in this case from the
right side). Due to the wing diehdral and (I think) due to the sweep back,
this creates a rolling moment to the left. Normally, the ailerons and roll
spoilers should allow to counter-act this, but in the picture (
http://www.airliners.net/uf/view.file?id=536882887&filename=phpOltUWB.jpg) I
see those controls are only partially deflected. Strange.
