After a few minutes of flying, he attempted two landings, both of which resulted in his performing a go-around. He said the third attempt appeared to be lined up well, but as he approached touchdown the wind became turbulent due to the buildings on the side of the runway. After touchdown, he lost directional control of the weight-shift controlled aircraft and it veered right, impacting a hangar. The aircraft’s keel beam was bent during the accident sequence. ## Factual narrative The pilot stated that the wind for takeoff was light and variable.
