Mink, the damage apparent in photos of the wing could be consistent with the loss of control of #1. We had a tanker a few years ago that suffered a bleed manidold failure in the leading edge of the wing. One of the "side effects" was a severed throttle cable. I believe the throttle remained in a cruise thrust setting and the crew ended up shutting the engine down with the fire switch. Not sure how the FADEC system on the Airbus is set up, but a loss of engine control certianly sounds consistent with the wing damage.
