Thanks to the eager beavers at JREF, I've got an update that pretty much debunks the 1994 gouge (unless JREF provided faked images which I doubt).
I wish Keith Thompson had been more careful in his research for the NEW WORLD ORDER FACTS documentary.
It looks bad on the whole movement when the errors are this significant.
Keith's supposed expose image from a 1994 U.S. Geological Survey;

The aerial view of the 9/11 Shankesville purported crash site;

According to Norseman, "The 94 photo was taken when they were backfilling the strip mine to reclaim it."
Clearly we aren't talking about the same two gouges but it's still an interesting coincidence regarding the proximity of the two sites.
I had a feeling the suggestive evidence was just too easy.
