Analysis

During a sight-seeing flt, the winds, outside air temp & propane gas burner temp began increasing, so the plt elected to land. He notified the chase crew, started a descent & anticipated making a 'drop line' landing. As the balloon began crossing over a dry river at about 200 ft AGL, it was descending at aprx 75 ft/min. The plt stated that at about that time, a downdraft forced the balloon to the river bed, then the wind dragged it into the river bank. Observers said the top of the balloon was suddenly distorted from downdraft. The plt stated everything was normal, then 'the wind hit the balloon' & there were 'no trees, flags, smoke or dust to anticipate the wind shear.'
