A Navy diver died at the bottom of a Maryland pond last year after refusing to leave his trapped fellow sailor to drown alone. Petty Officer 2nd Class Ryan Harris, 23, and Petty Officer 1st Class James Reyher, 28, were sent to dive in the Aberdeen Proving Ground on February 26 2013, but their lifeless bodies were pulled to the surface just 31 minutes after they started the dive. No one knew what had befallen the pair until an investigation, completed last year but only recently released, pieced together the final 31 minutes of the young men's lives.
