French tightrope walker crosses 300 feet above ground

French tightrope walker Tatiana-Mosio Bongonga stunned over 9,000 spectators after crossing a 400-metre wire stretched between two of Europe's tallest slag heaps in northern France. She walked without safety harness, around 300 feet above the ground and even performed acrobatic moves while crossing. A choir and musicians accompanied her daring feat before she safely reached the opposite slag heap.
