Possessing only scant amounts of war propaganda, Mariners of the Sky is the touching story of a naval officer who adopts a boy who is orphaned when his parents are tragically killed. The officer, played by the affable William Gargan, takes good care of the child, despite the low expectations of the child’s surviving relatives. The film then becomes charmingly absurd, because the child is kidnapped by a gangster who believes the child is his. Angry and motivated, Gargan marshals the entire US Navy to get back his little boy! An adventurous and warm film, Mariners of the Sky is as cute and cuddly as the Navy has ever been!
