Diver Survives Stingray Attack. Joe McKnight will no longer laugh at any jokes about Steve Irwinís death. Thatís because he survived his own encounter with a stingray. While diving for crayfish in New Zealandís Okiwi Bay, McKnight, 35, swam over a crevice and suddenly felt a stab on his leg. He looked down to see a three-foot-wide stingray attached to it. The stingray pulled away after five seconds, and there was a squirt of blood. McKnight described the pain as ďhaving a dead leg with a bee sting on top of it.Ē He thinks he provoked the sting by accidentally cornering the stingray. McKnight was released from the hospital within two hours with three stitches and a hole in his wetsuit as a souvenir.

New Options For Frequent Fliers. Undercurrent reader Jose Kirchner (Carmichael, CA) sent us a note that Japan Airlines has joined the oneworld airline alliance (including American Airlines, British Airways, Cathay Pacific and Qantas). Japan Air adds 47 new airports to the oneworld map, meaning divers can use their AAdvantage miles to some new Asia-Pacific destinations.

Fainting and Free Diving. A study in the International Journal of Sports Medicine says competitive free divers commonly faint or show other signs of poor oxygen circulation. In major free diving events held between 1998 and 2004, about 10 percent of competitors were disqualified due to severe signs of brain hypoxia, such as confusion, spasms and difficulty standing. The studyís author, Dr. Peter Lindholm of the Karolinska Institute in Stockholm, said free diving is risky compared with tennis or chess but not especially dangerous within the realm of extreme sports.
