Analysis

The commercial balloon pilot and a commercial rated passenger were making an overnight flight. The balloon was equipped with instruments and equipment that allowed flight following by los angeles ARTCC. The flight became engulfed in a cold front and endured heavy turbulence, strong up and down drafts, sleet, snow and freezing temperatures. Winds of over 60 knots pushed the balloon toward Utah. At daylight the plt attempted to land near Circleville, Utah. The passenger said the plt mistakenly pulled the 'red line' which dumped all the helium. The balloon fell at a rate beyond the maximum readings on the VSI.
