One "Why Question" I would like answered is: Why do training agencies no longer train divers to drop their weight belts when they are in trouble? He was on the surface! If he dropped the belt he might still be here. When I started OW my instructor said "If you are found dead still wearing your weight belt it is because you were a fracking moron and that cost you your life." This seems like a no brainer and yet an alarming number of divers are found dead still wearing their belts. DROP THE FRACKING WEIGHTS!
