On arrival from Frankfurt, the Boeing commenced a circling approach to runway 33 when, on very short final, a wind gust nearly drove the aircraft’s right wing into the ground. As the crew wrestled to right the airplane, the Boeing slammed down on the runway. A few seconds later the crew executed a go around and received a clearance to hold at the Salzburg VOR before deciding to return to Frankfurt. The Boeing landed there about an hour later without further incident. No injuries were reported.
