Analysis

The commercial balloon pilot was conducting passenger flights. A landing was being made on a parking lot with ten knots of wind and gusts to twenty knots. Just at touchdown a light gust caught the balloon and dragged it one hundred feet. One passenger chose to jump out of the basket and the basket rolled over him resulting in serious injuries. None of the other eight passengers left the basket and there were no other injuries.
