Analysis

The two balloons collided in mid air. One (N4195L) suffered a rip in the envelope which negated its lift, with burner full on. It descended at 500 RPM and made a hard landing. The hole in the envelope extended across 5 gore panels. The 2 balloons departed the same area with N4195L in the lead. It climbed slower and the other balloon (N5563L) overclimbed itand slid across the top of it. A bolt protruding from the metal basket of N5563L ripped the envelope of N4195L. N5563L was not damaged.
