Just saw this update over on Events at Sea:
The Colorado Springs Gazette reports that the jumpers were both trained for water survival. The 22 year-old-male is an Air Force Academy cadet with extensive training in water survival, which includes how to leap into the water from a high dive platform and how to stay afloat by inflating clothing with air. The 20-year-old woman is a trained lifeguard. This has led some to speculate that their going overboard was a stunt designed to demonstrate (two days before Congressional hearings) that the cruise industry could effectively and competently save passengers who go overboard.
Here is the
link to the full story. Looks like this might actually have been a staged stunt.
