The Ultramagic balloon pilot reported that, during a balloon festival, after a local sightseeing flight, he landed the balloon and decided to wait for the ground crew to locate the balloon before deflating. He added that, as the balloon was deflating, he "heard a basket sliding across the top of [his] balloon". The balloon rotated counter-clockwise and the balloon basket, still loaded with passengers, rolled upside down. The Ultramagic balloon sustained substantial damage to the burner rack. One passenger sustained serious injuries. The Lindstrand balloon pilot reported that, during landing, there were two balloons in his flight path. He added that he climbed and passed the first balloon, but was unable to pass the second. He reported that, "I brushed him with my basket on the top of his balloon." He landed the balloon without further incident. The Ultramagic pilot and the Lindstrand operations manager reported that there were no preaccident mechanical failures or malfunctions with the balloons that would have precluded normal operation.
