Most of these never hit the ground, thankfully, but a local school did get hit and we had to go on half-day sessions with them for a whole year. When the air-raid sirens would blow on our block, all the neighbors, kids and dogs ran out into the streets to see what was happening. Then if we saw something, we'd all go back inside our houses, under picnic tables in our basements and wait for the sirens to sound that it was all clear.
We never saw many hit the ground, because of course, we were hiding in the basement.
