Nakao wouId usually be called to the prison, would again ask names, age, rank, position to check the document received by Aihara from the KT. This information would be used by the Adjutant Section (Jin), Aihara and the Intelligence Section, which could so judge who was most important in the crew. Sugino had never attended interrogations, but sometimes Sato, Aihara and Entasu would. When Komori took the first PWs to KIU to be operated - Aihara may have been there, thinks he got in the front seat (of sedan, Komori and PW in back). 2-3 days later Komori called Nakao from the Intelligence Section, told him. that he was going to try a newly developed sleeping powder, said more flyers were to be taken to the University for experiments, that if the powder worked the flyers W would be drowsy by the time they reached the University, that he was going to give the powder to Goiyama, or perhaps Aihara, that he wanted Nakao-to help give the powder to the flyers, that Goiyama would get Nakao later in the afternoon.
