That is the same thing I have wondered. If all the documents were written in the early 70's it seems odd to me that in the mid to late 90's they were still available to be sanitized. Would these things have not been archived some were beside their original location by that time. It seems odd that they would not have cleaned out their file cabinets for well over a decade. Does anyone know were documents of this nature would have been archived?
This is nothing short of amazing they found these documents in an official file.
We had to send our documents to warehouses in D.C. from Wright-Patterson to archive which is why we destroyed rather than forwarded them in boxes to D.C. Chances of finding them again were remote at best.
There is no way any office I worked in would have had 30-year old documents stored. We ran out of space and cleaned out all the files in every office I worked in every year. I can still remember the General in our office going through his files from the 2-drawer safe he had every year to have room for the next year. First thing to go were copies of letters of appreciation to people, etc.
Thirty years of documents at the Headquarters would have meant the building would have been full of safes/file cabinets and very few people.
