What is all the fuss about? It is an old researchers' adage that that there are no secrets only lazy researchers.
The problem here is that the original source is an allegation in a press article and all that implies. It is not fact only a journalists view which may reflect his source and their agenda.
Some time ago I placed on this site a thread that gave the sequence, including code words, for the manning of Corsham in the 'Bolt from the blue scenario' which was deleted. This removal was on the grounds that the code words may be of use to someone. All of the information came from TNA files and was 50 years old.
So perhaps this is the wrong forum to expect balanced and informed judgement.
