When I watch documentaries on WWII bombing raids or even patrol missions they always talk about the unimaginable amount of ammunition shooting upwards at the planes. Did any of that ever fall back and hit people? Even in dogfights things like shell casings or debris from hit planes causing injuries?
hi! there's always room for more input on this, but you'll be interested in several previous posts on the impacts of anti-aircraft weapons and dogfights...
