Later, when all three children were safe on shore and the Coast Guard had cleared the beach, Simon and Hillary told reporters that they had heard a horn and loud cheers as they reached the small raft with a very frightened Xavier huddled inside, sobbing in terror. They were not sure what the commotion was; they were focused on bringing the boy safely to shore.
"Hey kid," Hillary remembers calling out, "It's OK. Don't worry. We'll help you," just as a strong wave crashed into the raft, spilling its occupant into the ocean. Flailing and screaming, Xavier disappeared briefly beneath the waves, but Simon dove beneath the surface to grab him as Hillary clung desperately to his board. They helped the little boy onto Hillary's board and together the trio paddled toward the beach.
"By this time," stated the Captain of the Florida, "the cutter had reached the shore, and two Coast Guard members swam with life buoys to meet the heroes."
