Reg, glad that my mention of Bicester brought the memories flooding back. With your intimate knowledge of the loos there you might be interested in this thread:

The Tech Site is fenced off and boarded up, but substantially the same as when you were there. It is the hope that it may be saved as is, restored, and then dedicated to telling the story of Bomber Command and the Bomber Offensive, ie your story, Phil's, and some 120,000 other aircrew. Can't say you'll find too many posts concerned with the ablutions at RAF Bicester, but feel free to add to the sum of human knowledge on that by adding to the thread! Seriously, great that you remember 13 OTU and its Blenheims. Hardly a sinecure posting though as some 8,000 of BC's aircrew died in training alone.
