I know nothing about the RAFAT sign, but note that the
Home of Number 1 Air Control Centre
sign has disappeared from the Main entrance of the place formerly known as RAF Kirton in Lindsey which is now a satellite of RAF Scampton and not to be called RAF Kirton in Lindsey under any circumstances (unless it's for mail deliveries, traffic directions or any other good reason).
I naturally assumed it had been robbed by Air Traffic at Leuchars (they stole stuff from Boulmer ISTR)!
