In the close confines of the Officer's Mess, Sqdn crewroom etc. this chap's personality and private life (divorcee, apparent womaniser, high social activity in the bar) must have been well known and gossiped about by his peers and senior officers. So what of his annual F1369 reports? Did they not indicate that he was perhaps drinking too much, a loose cannon maybe? Where were the checks and balances that keep a lookout for the odd maverick?
Or was he given enough rope....?
