“Cooper was frequently asked to take part in interrogations of pilots. The first time he did this, he and two other interrogators were sat behind a trestle table when the captured Luftwaffe pilot, wearing perfectly pressed Nazi uniform and highly polished jackboots, was marched in and halted in front of them. ‘He clicked his heels together and gave a very smart Nazi salute,’ said Jones. The panel was unprepared for this, none more so than Josh who stood up as smartly, gave the Nazi salute and repeated the prisoner’s ‘Heil Hitler’. Then realising that he had done the wrong thing, he looked in embarassment at his colleagues and sat down with such a speed that he missed his chair and disappeared completely under the table.”
