It is shown how recorder described made it possible to take vibration data from passenger passenger compartment of NC-135 jet aircraft with only few hours' notice prior to flight departure; eclipse monitoring camera mount was instrumented for vibration and combined flight and operation inputs indicated that hydraulic pumps would have to be relocated to keep vibration levels low; flight data measured on aircraft structural members are presented with samples of composite oscillographs along with complete bandpass peak distribution plots for several mission flight conditions.
