The one revelation that caused for me the most potential problem was the tag recovery event as depicted by Gentile. This is the event where Chatterton removed his single tank and pushed it ahead of him to enter the electric motor room to find the parts box with the famous U-869 tag on it. Apparently, someone entered the room BEFORE Chatterton, following a more direct and easier route, one that didn't require him to remove his DOUBLES! The diver apparently couldn't, or didn't make any attempt to find the parts box, but left behind a strobe. Gentile implies, but does not say outright, that Chatterton chose his route simply because it looked more dramatic on camera. If that were the case, then that does not speak well for Chatterton. However, he does not say whether Chatterton was aware of any other route, nor whether the other diver knew in advance that route existed or just happened upon it while exploring, nor does he explain why the other diver did not try to locate the tag himself. Whatever the case, Gentile poo-poos the entire incident anyway, stating that wreck divers knew "for years" the true identity of the sub, and that the tag retrival was "anti-climatic"
