This report describes methods of measurement and reduction of data on aircraft gun firings at high altitudes. These methods were applied to records obtained by airborne and ground based photogrammetric cameras for the purpose of determining a the spatial orientation of the gun at the moment of firing, b the spatial coordinates and velocity of the aircraft at the time of firing, c the muzzle velocity and the spatial coordinates of the point of burst of the projectile. Results of several rounds are tabulated and numerical examples of each type of computation are presented. A detailed description of the instrumentation is contained in BRL Report No. 1105, AD245372, Instrumentation for Acquisition of Ballistic Data on Full-Scale Aircraft Gun Firings, by Donald F. Menne, August 1960.
