Throughout his upbringing, Carl Gustaf appeared to have had serious differences in opinion with his family, with one author referring to him as the \"black sheep of his family.\" At an early age, Carl Gustaf was interested in mechanics; his subsequent fascination with flying machines was likely influenced by his uncle-in-law, who was a fighter ace during World War I (and later head of the German Luftwaffe). Von Rosen himself started his flying career as a mechanic before becoming an aerobatic stunt pilot in a travelling circus."@en .
