Probable cause

Failure of the pilot to maintain clearance from the tv tower due to improper in-flight planning/decision. Unfavorable wind/windshear and the tall tower were contributing factors.

Analysis

The plt said the acdnt occurred while he was participating in 'the national classics' with other hot air balloonists. He stated that while ascending, the balloon encountered wind shear that took it off course toward a tall tv tower. Subsequently, the balloon collided with the tower at about the 190 ft level, then it descended uncontrollably to the ground.
