The pilot of the balloon reported that, while landing, the wind suddenly shifted from about 1 to 10 miles per hour. The balloon ascended about 200 ft, then began to descend. Despite the use of both burners, the pilot was unable to arrest the descent. The basket struck the ground and tipped forward where she was partially ejected while pulling the deflation line. The balloon then began to ascend, and rotate, while the pilot continued to pull the deflation line. She was then fully ejected from the basket. Unable to hold onto the deflation line, she dropped about 15 to 20 ft to the ground and was seriously injured with a broken pelvis and three fractured vertebrae. One of the passengers continued to pull the deflation line and the balloon landed without damage. The pilot reported that there were no preaccident mechanical malfunctions or failures with the balloon that would have precluded normal operation. The pilot reported the forecast indicated calm wind at the surface.
