Two tidbits from AV Herald:
- "Passengers reported seeing sparks, possibly lightning, and a part flying off the right hand wing."

My dad was on this flight and he saw the part of the wing fly off. There were no injuries. The pilots said it was caused by extreme turbulence and excessive wind shear which was pushing the plane upward thank goodness. This also increased the speed and the pilots had no way of slowing it down. Due to the speed the wing flap, which was sticking up in preparation for landing, was detached. They were able to make it to Uruguay without a problem and they were scheduled to fly back into Buenos Aries once another plane can fly there and pick them up. Delta does not normally fly into Uruguay
