Interesting Ponderance.......maybe!

This may go down in Forum history as one of the most ridiculous, useless ponderances ever posted, but it really has me thinking.
And, you never know, maybe there is an answer!
During WWII, with all those fighters and bombers shooting literally millions and millions of various calibre MG and canon rounds at each other, especially over heavily populated areas of the major British and German cities, are there any reports, or at least, a batch of incidents where people or cars or whatever, have been hit by these 'wayward' projectiles.
OK, maybe after loosing the initial 'clout' from the load behind them, they would just be falling at 'terminal velocity'. But then, what is the 'terminal velocity' for lead or steel jacketed lead etc?
They would definitely be capable of causing some nasty injuries at whatever speed they fall.
Surely, considering the literal billions involved, some must have hit someone or something.
