The writer used the response times to the starting gun of the finalists in the 2016 Olympic 100m sprint event to confirm the THRESHER pressure-hull collapsed in less than the combined retinal plus cognitive integration times of those aboard; hence, they were not aware of the event.

In the response times of those eight runners, there appears to be a correlation between height of the runners and their muscular response times with the slowest being the tallest. Usian Bolt, a notoriously slow starter, is 6'5". He compensates for this disadvantage by achieving the highest speed ever measured for a runner during any sprint event: about 27 mph.

The link states the nerve signal transmission velocity associated with muscle action is 390-feet/sec or 4.7 inches per millisecond; hence, Bolt's added height above the shorter sprinters - who were about 5'9" - would only have added only about two milliseconds due to nerve signal transmission time - a value lost amid far greater differences in response times among the runners of different heights.

I have spent as much time as I have on this matter because no naval activity - including the Courts of inquiry - has ever stated that those aboard THRESHER and SCORPION did not drown or experience any physical pain when those pressure-hull collapse events occurred. Even now, those surviving relatives and friends deserve to be so informed.
