I thought one of the early stories from an Army whistleblower had to do with the aircraft flying into restricted air space around Site D in Pennsylvania (undisclosed addition to Raven Rock) and getting hit with air defense missiles. Even if an F-16 was the culprit, you would still see debris and not a black gash in the ground. I will have to find the thauce but I am pretty sure it was an old project camelot / avalon video.
