Lexa and Jake Mendenhall, on their first trip as certified scuba divers, made two one-hour dives before noticing that their boat was gone. They had been stranded with two instructors from the Thai diving company and another couple of novice divers.

"I kept thinking, 'What if there's no boat?  It's evening." Lexa Mendenhall told KHOU.

Apparently the boat captain had engine trouble and chose to go back to shore without them.
