premise: Warrant Officer Kenji Yanagiya (柳谷 謙治 , Yanagiya Kenji , March 1919 – February 29, 2008) was a member of the Imperial Japanese Navy's Zero fighter aces who fought the Battle of Solomon Islands in October 1942 – June 1943. He is best known as the only escort fighter pilot of the Yamamoto mission to survive the war.
hypothesis: Warrant Officer Kenji Yanagiya did not learn to fly until 1950.
reason: If he was a fighter pilot ace in World War II, and an escort pilot of the Yamamoto mission, he must have known how to fly long before 1950.
