The Answer to CAPT Harry Jackson's Musings

When CAPT Harry Jackson (1916-2005) – see Bona Fides below - was teaching a course in Submarine Design at MIT, he sometimes mentioned to his classes that in between sea trial test events on new Electric Boat constructed submarines, he would sit aft in the Engine Room and look around in the overhead, wondering what THRESHER’s crew were thinking/feeling when they saw the pressure hull coming in on them.

By applying the measured temporal asymmetry of the SCORPION's collapse event signal (bubble-pulse) and application of that value to THRESHER's bubble-pulse of 3.4 Hz, we now know that THRESHER's pressure-hull was completely destroyed in 0.047 seconds (47 milliseconds) or 1/20th of a second)

We also know from experiments discussed by the linked-site that human conscious processing takes place 200-300 milliseconds post stimulus, or more than four times the duration of the THRESHER's complete collapse.

As discussed by Chapter 2 of the manuscript of WHY THE USS THRESHER (SSN 593) EAS LOST – which some of you requested and received by email – it is further known that no sprinters during the trials and the final of the 2016 Olympic 100-meter event responded to the starting gun in less than 124 milliseconds.

So, there you have it. Although those aboard THRESHER knew collapse was imminent, they never knew it was occurring, and that's the answer to CAPT Harry Jackson's musings.

CAPT Harry A. Jackson, USN, recipient Harold E. Saunders Award for his significant contribution to naval engineering as set forth in the following quotes: “Combining his experience in the nuclear power program with the success of the single-screw Attack Submarine, Captain Jackson led the design and development of the deep diving, SSN 594 Class Submarines. This stands as the greatest advancement in performance and capability yet achieved in a single new class design. His design and engineering expertise were crucial factors in the successful development of the Fleet Ballistic Missile Submarine that currently is one of the Nation's primary strategic defense systems.”

“In his post-active duty career, Captain Jackson continues to direct his talents and expertise toward improving submarine design and engineering: as an advisor and counselor to Navy management; as an engineering consultant; and most importantly, as a teacher, passing on his expertise and experience to future Engineering Duty Officers and civilian engineers."
