Probable cause

Inadequate visual lookout by the student pilot (his failure to see & avoid). The transmission line and the student's lack of familiarity with the area were related factors.

Analysis

The balloon pilot was late to visually acquire a second set of power lines during a normal approach to land in a river bed. When he did see the second set of lines, he attempted to fly over them, but the balloon collided with the highest wire. The plt then made a successful landing, except he & the balloon had received flash burns.
