Analysis

The plts of a bucker jungmann, N1947G, & a pitts S-2B, N5302M, were practicing for an airshow. They began a maneuver called a 'mirror fly-by' in which the bucker was rolled upside down & the pitts was flown underneath it. Due to the air flow over the wings the acft were pushed apart as they flew in formation; however, the plts elected to modify the maneuver by having the pitts move forward. As the acft were positioned to where the wings were not overlapped, the acft converged into each other. Subsequently, the prop of the bucker struck the pitt's vertical fin & rudder, substantially damaging the pitts. However, both acft were landed safely.
