Gustaf Adolf passed studentexamen at Stockholm Palace in 1925 and attended the Cavalry Officer Candidate School (Kavalleriets officersaspirantskola, KavOAS) in Eksjö the following year and in 1926–1927 the Royal Military Academy.[15] He was also honorary chairman of the Central Organization of the Swedish Women’s Auxiliary Veterinary Corps (Centralstyrelsen för Svenska blå stjärnan).In his book Alla dessa Bernadottar (All these Bernadottes), Staffan Skott asserts that letters and diary entries by influential anti-Nazi Swedes disprove the rumors.[citation needed] Some leading Swedish politicians were averse to the possibility of seeing Gustaf Adolf inherit the throne, and one prominent Social Democrat publicly uttered that the prince was "a person who must never be king".[19] An investigation found that an inexperienced young employee had serviced the aircraft and, short of time, the plane's captain had failed to perform the final pre-flight check list properly.
