Analysis

The pilot stated the balloon was inflated and established weigh-off procedures were conducted. At the end of the weight-off procedure, as the balloon was being walked by the ground handlers, an increase in wind velocity caused the basket to be pulled free from their grasp. The balloons gondola was dragged across the ground for about 100 yards, collided with a portable stage, went up and over the roof of the stage, and collided with a tow truck causing a passenger to fall out before becoming airborne. It successfully landed about 13 miles north of the takeoff site. A national weather service forcaster at the site stated that winds were 180 degrees at 7 mph with gusts to 10 mph at 5 feet above the ground.
