Narrative:

It was a textbook approach in a C172. Flaps down, minimum airspeed. A small crosswind from the right. I paid no attention to the line of hangar buildings on the right which was a short distance from the runway. As my plane descended through an altitude even with the top of the buildings, the right wing lost lift and dropped. The plane slipped to the right completely off the runway. Instinctively I applied full power and put the nose down to regain airspeed, gained a few ft of altitude, flew back over the runway to make a textbook landing down the centerline. This happened with no time to think. My reflexes kicked in with the intensive stall recovery training I had.
