Forgive me, for I am but old and lacking in memory function. Is/Was the Filton Block the new (OK, it's not new now) one built in 1973, just next to the OM and on the other side, the Briefing Rooms etc? I was not pleased to be moved there from the OM as I had a corner room and was not sharing as my roomie had moved on!!
Out of interest, I'm sure I was on #169 Course, which ran from September 72 to July/August 73. But then again, I might have been somewhere else entirely!
