Previous research has produced a real-time, three dimensional, interactive moving platform simulator (MPS). The simulator utilizes Defense Mapping Agency digital terrain elevation data to generate the three dimensional terrain and runs on Silicon Graphics, Inc. IRIS 4D/70GT graphics workstations. The MPS system has been used as a basis for a variety of military applications. We present here how the MPS system was modified to be utilized as a crash investigation tool for U.S. Army aircraft mishaps. Flight recorder data from the mishap aircraft is used to graphically reconstruct the flight of the aircraft. Flight attitudes, gauge readings, switch positions, warning and advisory light indicators, and flight control inputs are displayed. The visualization of the flight recorder data greatly aids in the analysis of the causes of an aircraft mishap. in
