WW2 bomber crashes inside the US data?

I found this site through Google and figure it will be as likely as any to have a chance in helping on this question.

My grandmother had a story she used to tell of when a bomber crashed on her land.  There was some kind of trouble in mid-air and the pilots had to parachute out and took cover behind the chimney of my great-grandfather's house as the plane fragments and bombs impacted.  The military closed off the area and cleared away the debris, but-- as I was told-- bombs and bomb fragments continued to be plowed up for years afterward.  There has been one "bomb fragment" kept in the family ever since.

My grandmother died on Dec. 31st and I've been thinking a lot about family history.

Not doubting the story at all, but needing to have a skeptical eye for the "bomb fragment", I pulled it out from under the floor to take a closer look at it today for distinguishing marks.  After all, just because it was plowed up in the area of an accidental bombing doesn't mean that it has to be part of a bomb-- could be a fragment of old farm equipment or pretty much anything.  So I examine the fragment-- no markings on it.  But there are threads, and a loop.  Threads are something I would have expected, for screwing on a warhead.  A loop?  Hadn't thought of it (having thought the bombs would have just been stacked in a cargo bay) but a loop could have been used to hang a bomb from a plane.  So I start googling around for photos or diagrams of US WW2 bombs.  And found this:

The loops on this bomb look pretty damn much like the loop on my fragment-- and are positioned near where the threads would be, too.

So I'm pretty sure that I've already answered one of the questions I was going to ask-- if it was really a bomb fragment.

Which leaves my second question-- is there any on-line resource to give me information about this crash?  It happened in 1943 and it happened here:

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.

Unable to solve this one--not enough info.
