Imagine surfacing from an ocean dive only to discover your boat is gone and you're completely alone. This scary situation actually happened to Tom and Eileen Lonergan on January 25, 1998. Tom and Eileen Lonergan were experienced divers on a trip to Australia's Great Barrier Reef when their dive boat crew left them behind. Two days passed before anyone realized they were missing, and rescue teams searched for the married couple unsuccessfully for days. The two were never seen again, their bodies assumed to be lost at sea.
