Me: Perhaps not a bomb at altitude if “only” 5 acres?
A five acre square would only be about 155 yards on a side, that sounds like scattering upon impact, certainly not from an explosion at altitude. Five acres is NOT a very large area, to anyone who grew up in farm country it is a postage stamp size lot. There is a QVC distribution warehouse near here that covers over TWENTY acres and that is just the building itself, not the parking lots etc.
