I'm FSO of a UK airline. I would suggest that you produce an edition of what you propose and distribute it to senior management. You may have already done this, in which case apologies, but by letting "them" see what information is actually going to be disseminated you may put their fears to rest. It is worth pointing out that any investigative journalist worth his or her salt (are there any?) could dig up any incidents involving your airline from official publications. Perhaps if you were to offer to produce a limited number of copies, for distribution to crew rooms only?
