RESULTS
Performance of Instrumentation and Recording System
Of the 22 air-pressure measurements attempted on Mike shot, 10 were completely successful and 3 partially so; on King shot, 9 of the 14 measurements attempted were entirely
successful and the remaining 5 partially so. Consequently it is felt that enough satisfactory
records were obtained to justify the conclusions reached in this report. It was necessary,
however, in analyzing the data from both Mike and King shots, to exercise considerable personal judgment because of several unforeseeable failures of the recording and gauge systems.
On Mike shot three of the eleven recorders failed to start at all because the brakes on the
tape transport system jammed. These brakes consisted of asbestos brake bands around soft
iron brake drums; the extremely high moisture content of the air in the recording shelters
prior to Mike shot apparently caused the brake bands to swell and the drumsto rust, with the
