I really do hope that the DM has got it wrong otherwise we have an officer giving evidence under oath saying that another officer who was a member of a SI threatened him with physical violence unless he lied when giving evidence to the SI. If true I'm not sure what it says about 'just culture'.
I also hope that Flt Lt Townshend is acquitted and Beags and others can say 'I told you so'. The alternative is that one of the most senior AT pilots in the RAF was stupid enough to lie/cover up or whatever... again 'just culture'!
