Analysis

The student pilot was on an authorized three segment cross country flight. The helicopter was observed flying southbound along a highway, 9 miles south of the second segment destination airport. At 150 feet a.g.l., the helicopter struck the bottom wire of a three wire set of transmission lines that spanned the highway. The helicopter then fell into the southbound lanes of the highway. It was immediately struck by a military humvee vehicle that was the second vehicle in a convoy. Both the humvee and helicopter parts were intermixed and destroyed by an intense post crash fire when they came to rest at the side of the highway. The driver of the humvee was not injured.
