Don't close the thread. I don't think there has been any breach of OSA or SOP's on this thread, all that I can see is "ask a stupid question, get a stupid answer".
Totally agree that if anything too close to the knuckle is posted then any thread should go, indeed I have been surprised how long some have been allowed to run, (suppose you can argue that deleting it would confirm the info, but what's to stop someone speculating until they get it deleted).
It's been said plenty of times before, this is a public forum and you must assume that everyone is reading it. Everyone current or Ex Mil. is professional enough not screw up on here, I hope.
Those that know the answers know not to say anything at all sensible in reply, situation normal!
