This is The ASTerisk, specifically set up with capital AST designated for Aviation Survival Technician. 

In this episode of the ASTerisk, we take a look to how and why the USCG Rescue Swimmer program began.  We discuss all the training a USCG Rescue Swimmer has to go through, from putting your name on the "A" School list, to attending school, to become a swimmer, to the training thereafter.  We go into a little of my own history and experience in AST "A" School and getting fully qualified as a USCG Rescue Swimmer.  Enjoy!
