However, in a crater forming meteorite, individuals are usually not found near the crater vicinity but strewn further away since they are a product of early fragmentation. So individuals could be a part of this meteorite, but not discovered yet. Secondly, have you seen the size of some of the fragments from this crater? They are huge! I am no munitions expert, but I would think that the largest WWII bombs would produce shrapnel the mass and thickness of the largest pieces. Finally, please take a look at Mirko's beautifully prepared slices and endcuts. In them you will notice distinct inclusions that appear to be Shreibersite. Now, I have never known a man-made metal to have inclusions of Shreibersite in them.
