So, I entirely failed to keep up my daily diary covering my later days in Abilene and the return to the UK....which all happened over a fortnight ago.
The main reason was, as has happened on previous research trips, the final couple of days assumed a new level of intensity. I had more specific information to find - and indeed found much of what I was looking for.
Suddenly seven hours in an archive wasn't enough, and my evenings were spent reading around my subject and trying to pull all my thoughts into order.
I headed home on a high - only to have my wings filled with flak at the Brunel Research Presentation event on my return.
My head was still filled with the connections from Bikini Atoll through the U2 and Corona to NASA - but I didn't articulate those linkages particularly well, and was rather forensically pulled apart by the great and good of my department.
I'm confident the hypothesis works and that I have the evidence to support it. The next few months will be a matter of unpicking all that evidence from the documents i collected and beginning to develop a coherent narrative.
