I was also there that day when it happened. Basically, there was a rather strong crosswind blowing on that particular day.
As the aircraft made the final 47 degree right turn to line up with rwy. 13, it veered significantly to the left of the normal approach path. As the pilot tried to correct his heading, he overdid it and swung WAAAAAAY to the right of the runway centerline (note that the aircraft was already over the runway by now). The jumbo then went into a rather steep left bank with a slightly nose-down attitude as the pilot tried to re-correct his heading and to kill off excess altitude. The aircraft lost altitude rather quickly, and before the wings could be leveled, the No. 1 engine had struck the runway surface (look closely at the top picture -- the left ailerons were all the way down while the right ailerons and spoilers were fully up). The plane then bounced right back into the air and sort-of drifted down the runway at an altitude of approx. 40-50 feet for a couple more seconds before it finally did a go-around. By now, flames can be seen coming out of engine no. 1.
Over the radio, the pilot announced that the damaged engine had to be shut down. About 20 minutes after the first failed attempt, the plane returned for its second try. Believe it or not, it practically repeated its moves from the first attempt, but thankfully this time, it touchdown without slamming another engine on the runway or worse.
Another classic case of failing to do a go-around when one should have!! I heard a rumor that the pilot either got demoted or sacked after this little episode.
