I figure JIV was looking to see the RTS in the Public Domain.
Interestingly when I did a bit of work on the Chinook in 2010 the classified insert for the RTS including the SOP was openly published on the www for all to see. if you knew where to look and the DRTSA (RW) team pointed you in the direction you could find it. I just tried now and it has disappeared. In my little bit of the FW domain we used to distribute numbered hard copies. Not that good at Google but whilst searching I came across the link to Desider (The DE&S House rag) from Nov 2010. An article full of aspirations and some good pictures of RJ and also the R over Lincoln.
