A squared: I think you read my post too fast . I was not making statements but asking questions not being familiar with US airspace .
Thanks for your answers , so in this scenario, uncontrolled airport , asuming the circle around Berkley Co on the map above is class E , if this was in my country both aircraft would have been on the Berkley co "advisory frequency " ( which we call in here A/A or auto info ) .
In my country if a military jet is low flying above a VFR uncontrolled airport , it makes a short call before entering stating position , heading and altitude . You do not do this in the U.S. ?
Again this might have been done in this case , as even doing this is no guarantee you will not have a collision .
Big case of bad luck still hits you sometimes even if you do everything right.
