"Being found is about being seen, right?" Molthen asks, reminding me of cases where we flew directly over people – several times – whom we didn't see. Despite the newest infrared and night vision technologies, it can be extremely difficult to see something as small as a raft, or just a person, in the vast ocean. Nick Schuyler, the lone survivor of a capsizing off Florida's Gulf Coast, recently co-wrote the book Not Without Hope. In it, he describes how he and former NFL defensive end Corey Smith waved their life jackets at several passing search aircraft without ever being seen. A U.S. Coast Guard cutter finally spotted Schuyler, sitting on the hull of the overturned boat, after Smith and two others had died.
