Re:WW2 bomber crashes inside the US data?
The nearest date I can give is 1943-- the reason I can give that is that the detail my mother was "still nursing" at the time and my grandmother's boss at work thought the whole "bomber crashing in my yard" thing was an excuse to be home with her daughter. My mother was born in June 1942, and "still" nursing implies towards the end of nursing, so that's how I know it has to be 1943.
The location is between Greenville, SC and Anderson, SC. Greenville most likely location for the base.
