I think it's a fact that some people manage to slip through the net at Cranwell; people who, by any definition, are extremely poor officers, lacking in manners, commonsense and decency.
However, I'm sure the same was the case 10, 20, 30 years ago, by the definitions applied then. On the whole we're dedicated, professional, determined, and intelligent. Society changes, as does the pool of people who are available and suitable to hold the Queen's Commission.
