Being fascinated by submarines I couldnt resist reading this tale of horror. The book is in effect the biography of "Swede" Momsen, who pioneered rescue techniques for submariners. The atmosphere the author creates is terrific, the feeling of helplessness the crew of a sunken experience is conveyed in full. The frustration Momsen felt when his brilliant ideas sat untouched on the shelf in the Navy Headquarters is conveyed brilliantly. When he takes up a new post and stumbles across his own work unaddressed and ignored the anger comes across. Terrific book.
