During the flight the groundspeed of the balloon increased to an estimated 12 knots, and the pilot decided to land in a showground. This area was surrounded by large trees. In the final stages of the landing attempt, the balloon was affected by a windshear and began to sink. The pilot activated the burners but the balloon struck a 15 metre high tree. Fearing that the balloon would overshoot the planned landing area, the pilot activated the rip panel. A heavy landing resulted and the basket rolled over in the direction of flight. One passenger was thrown from the basket and received a broken leg.
