Great story about the first submarine to dive and resurface on its own. It was discovered several years ago by a fisherman in Panama, and later confirmed by Jim Delgado (director of Vancouver Maritime Museum) to be Kroehl's "Sub Marine Explorer". He used it to find pearls in the oyster beds.
Sadly he passed away a few years later in Panama from "the bends" (decompression sickness). Little was known about the need to ascend slowly to prevent it. A very dangerous venture that cost the crew their lives.
