While the other divers intended to pick a spot and search for a tag or other piece of identification, Chatterton planned to swim the wreck, orienting himself according to his Chicago memories, looking for nothing but impressions. Only when he understood a wreck did he believe he could formulate a plan to approach it. The strategy made it likely that another diver would beat him to the sub’s identity, but Chatterton was willing to take the chance. He staked much of his diving on the principle that preparation came first, so he would not just start digging in hopes that he might get lucky.
