With regards to my earlier post which mentioned a book I bought a few years back and thoroughly enjoyed...I now know it was one of Paul Crickmore's.
As a point of interest, if anybody is after his latest book 'Lockheed Blackbird - Beyond The Secret Missions' (pub 2004, 400 pages HDCV) then have a hunt on eBay or PM me and I'll give you the direct link...
...It's worth reasonable coin these days but I found a couple of new cheap copies (15 pounds, bought one myself) being sold by a UK eBay seller. It's regarded as one of the ultimate SR-71 publications, check Amazon to get an idea of what it's worth second-hand
