 The reason that the special flight officer probationary cadet had to answer such a survey rather than send the applications at their own will was because the military had known that the students who had come from college had a wider vision, and would not easily apply for such a mission.Some college graduates, who did not volunteer willingly, were pressured to circle ""desire earnestly"" in the survey.Many former students from Japan's elite colleges such as Tokyo, Kyoto, Keio and Waseda volunteered as kamikaze pilots in World War II.
