Description

My grandfather(Poppy) died last year. I knew he worked for OSI for a long time, had clearances, etc. I know Wright-Patterson Air Force Base comes up in the lore quite a bit. I was hoping someone more versed might have some insight on the time periods mentioned by my grandmother ('63 to '67 and '81 to '84). I haven't been into this topic very long, so I am not that versed.
I know when he retired from OSI he went forward to work for GE Aircraft Engines, still cleared, which I assume is one of the complex companies? I think he fully retired in the early-mid 2000s. I feel like he kept the clearance for quite a few years after that even. I'm not sure he had any documents or odd belongings at the homeplace. But I also wouldn't know what to look for to begin with. Is there anything in particular to look for from Wright-Pat or the OSI? My grandmother still has access to most of his belonging and it is at least 35 years worth of stuff.
