Last month, we told you about the two Coast Guard divers who drowned during a reported cold water familiarization exercise 500 miles north of Barrow, Alaska. On August 17th, while many of the crew relaxed topside, Lt. Jessica Hill and Boatswain's Mate Steven Duque went for a dive off the 420-foot icebreaker, the Healy. A support team held ropes tethered to the divers, and several research scientists watched from the deck. Apparently:

• The pair had been underwater for about 10 minutes.
• Something appeared to be wrong, so they were pulled from the icy water.
• EMTs immediately performed CPR.
• The divers were carried to the ship's sick bay, where they were pronounced dead two hours later.

After more than a month, no one is able to explain what happened to the divers. In the meantime, the Coast Guard has started two investigations -- one, focusing on the cause of the accident; another, a broad administrative investigation that could result in findings of responsibility -- and has relieved the Healy's captain of duty. The Coast Guard has also removed all diving equipment from the ship, and suspended all polar diving. Despite this, the Coast Guard has refused to release any information about the event, and the families of the divers can't even get death certificates. Weird? Conspiracy? CYA? What do you think?
