A chum of mine told a tale against himself which he always said showed "airman tendencies".
In his first (unsuccessful!) go at OASC, when told in interview that he could smoke (how unbelieveable does that seem now!), he produced his packet and lit up. In his own words: "I don't know which was worse - not offering the interviewer a ciggie or lighting up a half-smoked one that I had saved!"
But then he did retire as a squadron leader......
