...Waller: Well, for example, the digital display indicator was broken. That's a digital screen that shows the sub's executive officer and captain the same sonar picture that the guys in the sonar shack are looking at. Having that screen broken was obviously not helpful. Then, down in the sonar shack, there should have been three or four sonar technicians as well as a supervisor keeping an eye on things. But that day on the Greeneville, there were only two technicians...
...crew of the Greeneville, who should have been concentrating on a rapid surfacing drill, and the demands of entertaining the civilians apparently threw the submarine's rigid procedural schedule dangerously off-target. There were also mechanical problems from the outset; Griffiths reports that a screen meant to display sonar readings to the commander and others on deck was not working, but when officers discovered the malfunction, they decided to put off repairs until returning to port...
...course, human error may have played a significant role in the collision as well. After an extended on-board lunch with the civilians, the crew was left with little time to perform a critical periscope check, Griffiths said, and just before the collision, the sonar room was left without its supervisor, who was assigned to be a "tour guide" instead of watching over a trainee manning the sonar display. The continuing inquiry could have serious repercussions for several officers on board the sub, including Cmdr. Scott Waddle, who last week spoke exclusively to TIME about the collision - and the aftermath...
...There were so many things, like the sonar malfunction, the emphasis on rushing through the procedures - individual things that were fixable when they happened. If a certain sonar display wasn't working, for example, maybe the trip should have been canceled. If the morning was drawn out, and there wasn't enough time to go through the afternoon's activities, maybe someone should have said something to that effect...
...officers were flabbergasted by the disaster and privately were quick to blame Waddle. Although 16 civilians were aboard, they did little more than "pretend to drive" the submarine during the rapid ascent drill, Navy officers said. Waddle and his crew were still responsible for scouring the surface with their sonar and periscope before launching the "emergency main ballast blow." The choppy waters and the ship's white color may have made detecting the trawler difficult. But Navy officers said that if, as the trawler's crew said, their vessel was steaming at 11 knots, it should have been generating enough...
