When the cold September sea reached out her icy fingers to claim fisherman John Roberts, a plastic boat in a cozy British pub came to his rescue. Just as Roberts began to think he would succumb to the Atlantic's numbing clutches, his spirits were buoyed by the sound of flares going off above the Royal National Lifeboat Institution (RNLI) station in his home port of Sennen Cove. "When I heard those two bangs and knew what they were, then I knew somebody was coming for me," said the 53-year-old veteran of England's treacherous southwestern coastal waters. Roberts insists he owes a debt of gratitude to the RNLI and the Royal Navy helicopter that plucked him from the sea.
