National Aeronautics and Space Administration (NASA) Space Shuttle Columbia Accident Investigation
NASA: The Columbia Accident Investigation Board released their final report - see CAIB Report
Chapter 10, Sec. 9 deals specifically with the intermittent, explosive-bolt cabling problems which were experienced on multiple shuttle launches prior to the Columbia disaster, which were subsequently tested and isolated by Universal Synaptics Intermittent Fault Detection testing at Kennedy Space Center.
10.9.3 synopsis: "Today's test and troubleshooting technology" [Universal Synaptics IFD] "may have improved the ability to test circuits and potentially prevent intermittent failures"
Observation: "NASA should consider a redesign of the system" "or conduct advanced testing for intermittent failure" using IFD testing capabilities.
