Two Americans and an Austrian attempting a skydive at the South Pole died when their chutes failed to open properly. The victims--Steve Mulholland, 36, of Seattle and Ray Miller Jr., 43, of Tiffin, Ohio--were among six skydivers on the jump organized by Adventure Network International. They jumped from a Twin Otter aircraft at about 8,500 feet, Michael McDowell of Adventure Network said. Two hit the ground without their parachutes ever opening, and the chute on the third did not open fully, McDowell said. Their three companions--an American and two Norwegians--landed safely.
